Reaction Steps
2-(4-Bromophenyl)-N-[2-(1-piperidinyl)ethyl]-3H-imidazo[4,5-b]pyridine-3-acetamide (3.5 g, 0.0079 mole) was converted to the hydrochloride salt in isopropyl alcohol-isopropyl ether, using concentrated hydrochloric acid to acidify. Recrystallization from isopropyl alcohol-isopropyl ether gave 3.5 g (83%) of a white solid, mp 150°-153° C.
