Abstract
Pantetheine is obtained by reacting a mixed anhydride of carbo-aralkoxy-b -alanine or an alkyl ester of carbo-aralkoxy-b -alanine with an aralkylthioethylamine, e.g. 2-benzylthioethylamine in the presence of an inert solvent to produce N - (carbo - aralkoxy - b - alanyl) - 2 - aralkylthioethylamine, removing the aralkyl and carbo-aralkoxy groups from the N-(carboaralkoxy - b - alanyl) - 2 - aralkylthioethylamine by hydrogenolysis and reacting the resulting amino-thiol, N-b -alanyl-2-mercaptoethylamine, with pantolactone to produce pantetheine. The aralkylthioethylamine is reacted with the mixed anhydride of carboaralkoxy-b -alanine in the temperature range 0 DEG to 20 DEG C. and with the alkyl ester of carboaralkoxy-b -alanine in the temperature range 50 DEG to 150 DEG C. As mixed anhydride of carboaralkoxy-b -alanine there may be used an azide, chloride of sulphuric anhydride. The hydrogenolysis may be effected with alkali metal, e.g. sodium and liquid ammonia. The N-b -alanyl-2-mercaptoethylamine is reacted with pantolactone at approximately 100 DEG C.
