실험 절차

A stirred solution of 1 part of 5-chloro-1-{1-[3-(1,3-dihydro-2-oxo-2H-benzimidazol-1-yl)propyl]-4-piperidinyl}-1,3-dihydro-2H-benzimidazol-2-one in 20 parts of ethanol is saturated with gaseous hydrogen chloride. The formed hydrochloride salt is allowed to crystallize while stirring. It is filtered off and dried, yielding 0.6 parts (53%) of 5-chloro-1-{1-[3-(1,3-dihydro-2-oxo-2H-benzimidazol-1-yl)propyl]-4-piperidinyl}-1,3-dihydro-2H-benzimidazol-2-one hydrochloride hydrate; mp. 195.7° C.
