Abstract
Procedure for obtaining 2,6-diacyloxymethylpyridines of general formula (I) **(See formula)** where R1 and R2 are identical and signify hydrogen or alkyl -L C with 1-4 carbon atoms from pyridine derivatives of general formula (II) **(See formula)** where X signifies a halogen atom, characterized in that the pyridine derivatives of general formula (II) where the meaning of X is as indicated above, are reacted in the presence of organic solvents with the minimum molar amount calculated on the halogen, of a tertiary amine and an aliphatic carboxylic acid with 1-4 carbon atoms at temperatures between 0ºC and the boiling point of the reaction mixture, the obtained product is isolated from the mixture and, if desired, purified.
