ABSTRACT:
5-Methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine-2-carboxylic acid of formula (5) or a salt thereof,is prepared by reacting reacting 2-bromo-5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine of formula (3) or a salt thereof,with a metal cyanide, to obtain 2-cyano-5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine of formula (4) or a salt thereof,and hydrolyzing the 2-cyano-5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine of formula (4) or a salt thereof.
