Abstract

Procedure for the preparation of a pyridoxine derivative, of the crude formula (see formula), characterized in that amounts, approximately stoichiometric, of glyoxylic acid previously supported are reacted in an inert material such as celite, decalite and the like and containing 1 mol of glyoxylic monohydrate, with pyridoxine, making the mixture it is solid state and interposing absolute alcohol, heating the mixture, filtering with charcoal, performing the subsequent washes with 20% of the volume of the alcohol used leaving the filtered solution, protected from light, and subjected to agitation for approximately one night, getting a white crystallized product.
