Abstract
Compounds of the general formula <FORM:0972961/C1/1> (wherein R represents an optional alkyl, alkenyl or aralkyl substituent, R1 represents an optional alkyl substituent, R2 represents an optional alkyl, alkoxy, trifluoromethyl or halogeno substituent, R3 represents an optional trifluoromethyl, alkyl, alkoxy, alkylthio, hydroxyalkylthio, halogeno, nitro, amino, alkylsulphinyl, alkylsulphonyl, hydroxy or acylamino substituent and R4, which can only be present when R3 is other than a trifluoromethyl substituent, represents an optional alkyl, alkoxy, alkylthio, hydroxy-alkylthio, halogeno, nitro, amino, alkylsulphinyl, alkylsulphonyl, hydroxy or acylamino substituent, and the broken lines denote the bonds to the optional substituents) are prepared by reacting a 2-aminobenzophenone betaoxime of the general formula <FORM:0972961/C1/2> (wherein R30 and R40 have any of the values accorded to R3 and R4 except amino) with an a -halogenoacyl halide of the general formula <FORM:0972961/C1/3> (wherein X and Y represent halogeno substituents) in the presence of more than one mol of an acid-binding agent and, in the case where R30 and R40 were absent in the starting material, subjecting the benzodiazepine formed to one or more of the steps nitration, reduction of the nitro group and acylation of the resulting amino group where it is desired to introduce a nitro, amino or acylamino group or, in the case where one or both or R30 and R40 were nitro groups in the starting material, subjecting the benzodiazepine formed to one or both of the steps of reduction of the nitro group or groups and acylation of the resulting amino group or groups where one or two amino or acylamino groups is or are required in the product. The reaction proceeds through an intermediate acyl amide which can be isolated when the reaction is carried out stepwise using one mol of the acidbinding agent in the initial step. The preferred acid-binding agent is sodium hydroxide. 2-Chloroacetamido -5- chlorobenzophenone betaoxime is prepared by condensing 2-amino-5-chlorobenzophenone betaoxime with chloroacetyl chloride in the presence of approximately 1 mol of sodium hydroxide. Specification 972,968 is referred to.
