Definitions
- the present invention relates to a process for the preparation of fenofibrate.
- Fenofibrate whose structure corresponds to the formula:
- the fenofibric acid of formula it is also possible to prepare the fenofibric acid of formula: then to transform it into an ester, in particular by going through the preparation of the acid chloride by the action of cold phosphorus pentachloride (0 to 5 ° C.), then reacting the desired alcohol. According to the described tests, the acid chloride is isolated and recrystallized prior to any other transformation. Fenofibrate is prepared by esterification in a sulfuric acid medium. It is stated that the preferred method is transesterification.
- the fenofibric acid chloride is prepared in situ by the action of a chlorinating agent chosen from all the agents known to allow the realization of such a reaction, which do not affect the rest of the molecule, in particular it is selected from thionyl chloride, sulfuryl chloride, oxalyl chloride, carbonyl chloride, phosphorus trichloride or phosphoryl chloride. It is understood that the chlorinating agent makes it possible simultaneously to carry out the chlorination and dehydration of fenofibric acid of general formula (II).
- the fenofibric acid chloride is prepared in situ by the action of thionyl chloride, sulphuryl chloride, oxalyl chloride, or phosphoryl chloride and among these agents, more particularly thionyl chloride.
- the method according to the invention is implemented without the addition of a solvent.
- isopropanol is used both as a solvent and as a reagent.
- the method according to the invention is implemented in the presence of a base.
- the base may be an alkali metal carbonate or hydroxide, particularly an alkali metal carbonate such as potassium or sodium carbonate, or sodium or potassium hydroxide; the base may also be an amine, preferably a tertiary amine, and among tertiary amines, especially triethylamine or pyridine or their derivatives.
- the process according to the invention is carried out at a temperature of 60 to 90 ° C.
- the process according to the invention is carried out with an excess of chlorinating agent (thionyl chloride, sulphuryl chloride, oxalyl chloride, carbonyl chloride, triphosphorous chloride). or phosphoryl chloride).
- chlorinating agent thionyl chloride, sulphuryl chloride, oxalyl chloride, carbonyl chloride, triphosphorous chloride. or phosphoryl chloride.
- it is carried out with an excess of thionyl chloride, sulfuryl chloride, oxalyl chloride, or phosphoryl chloride.
- the process according to the invention is carried out with an excess of thionyl chloride.
- the preparation of the acid chloride is advantageously carried out in isopropanol, preferably in the presence of a slight excess of chlorinating agent, for example in the presence of an excess of thionyl chloride such as the ratio of thionyl chloride fenofibric acid is between 1, 1 and 1.5.
- the temperature is in general between 60 and 90 ° C., preferably between 80 and 90 ° C. It is not necessary to add a solvent, the isopropanol serving both solvent and reagent. From its formation, the acid chloride reacts with isopropanol to form the expected fenofibrate, especially at a temperature between 60 and 90 ° C.
- the reaction can be carried out in the presence of a base such as a carbonate, such as, for example, potassium or sodium carbonate, or in the presence of an alkaline hydroxide such as, for example, sodium or potassium hydroxide; the base is used to neutralize hydrochloric acid at the end of the fenofibrate formation reaction.
- a base such as a carbonate, such as, for example, potassium or sodium carbonate
- an alkaline hydroxide such as, for example, sodium or potassium hydroxide
- an organic base of the amine type in particular tertiary amine, for example triethylamine or pyridine or their derivatives.
- the process according to the invention is particularly advantageous because it provides a very improved yield and because it can be operated at a moderate temperature. The reaction is fast and clean, it does not require the recrystallization of the product after treatment.
- Fenofibric acid of formula (II) may be prepared as described in British Patent Application GB 1,539,897.
- Reactor A In a 250 ml double-jacketed reactor (Reactor A), 60 g of fenofibric acid (1 eq; 0.188 mol) are introduced and 120 ml of isopropanol (2 volumes). The reaction mixture is refluxed. The reaction mixture is heterogeneous. 29.11 g of thionyl chloride (1.3 eq, 0.245 mol) are added to this suspension in 3 hours. The reaction mixture is homogenized during the addition of thionyl chloride to give a yellow solution. At the end of the addition, the reaction mixture is kept under reflux for about 4 hours (the kinetics of reaction is followed by HPLC).
- reactor A The contents of reactor A are poured hot into reactor B in about one hour.
- the reactor A is rinsed with 15 ml of isopropanol which are transferred to the reactor B.
- the mixture is stirred for a minimum of 5 minutes. Stirring is stopped and the mixture is allowed to settle.
- the lower aqueous phase is removed.
- 134 ml of water are added to the alcohol phase, maintaining the temperature of the reaction mass at 60-65 ° C.
- the reaction mass is cooled to 50 ° C. and primed with a few mg of fenofibrate.
- the mixture is kept approximately 30 minutes at 50 ° C.
- the medium crystallizes.
- the temperature is cooled to 0-5 0 C in 2 hours and then kept at least 30 minutes at this temperature (0-5 0 C).
