Participants

Reaction Steps

A mixture of 4.1 g of 7-ethoxycarbonyl-2-phenyl-5,6,7,8-tetrahydroimidazo[2',1':2,3]thiazolo[5,4-c]pyridine hydrobromide and 50 ml of a solution of hydrobromic acid in acetic acid (20% (w/w) hydrobromic acid) was heated on a boiled water bath for 2 hours. The precipitated crystals were filtered off and washed with a mixture of ethanol and n-hexane to give 3.9 g of 2-phenyl-5,6,7,8-tetrahydroimidazo[2',1':2,3]thiazolo[5,4-c]pyridine dihydrobromide, melting at 315°-316° C. with decomposition.
