Abstract

Improvements introduced in the object of the main patent No. 387,410 granted on March 8, 1973 for: "Procedure for the preparation of new pyridoxine monoester salts" that respond to the following general formula: **(See formula)** in which: - A and A1 each represent: an alcoholic radical comprising a chain up to C16 or an aminoalcohylene radical of the formula: **(See formula)** hydrogen atom or a CH3CO group; - where p 1 2 2; -R1 and R2 each represent an alcohol radical containing up to 5 carbon atoms, said radicals being separated or incorporated in a heterocycle that encompasses the contiguous nitrogen atom, -Ac represents a pharmaceutically acceptable acid; n is an integer equal to 1,2 or 3; These improvements comprise the succession of the following steps: a) condensation of the α-4-3-0-isopropylidene-pyridoxine with the corresponding acid anhydride according to the formula: **(See formula)** b) transformation of the complex acid obtained into acid chloride using thionyl chloride, according to the following scheme: **(See formula)** c) condensation of the acid chloride with the corresponding dialcoylaminoalcohylic portion, according to the scheme **(See formula)** (Machine-translation by Google Translate, not legally binding)
