Abstract

Process for preparing thiamine derivatives of the general formula (I): ** (see formula) ** In which R (which may be in the various positions of the benzene ring) is hydrogen, halogen or lower alkyl, and its salts of pharmacologically acceptable organic and inorganic acids, such as hydrochlorides, hydrobromides, sulfates, phosphates, acetates, propionates, succinates, tartrates, citrates, salicates and the like, Characterized in that it is reacted in aqueous, hydroalcoholic or hydroacetonic solution of thiamine chloride hydrochloride with the corresponding halomethyl esters of the general formula (II): ** (see formula) ** In which X represents halogen, particularly cl or br, and R has the meanings shown above, under slow addition of alkali metal carbonates or ammonium carbonate.
