Procedure
To a solution of 6-chloro-1,3-dihydro-1-(2-piperidinoethyl)-2H-benzimidazol-2-one in ethanol (30 ml) was added concentrated hydrochloric acid (330 μl ) and the mixture was allowed to stand for 4 hours. The separating crystals were collected by suction and dried at 60° C. under reduced pressure to give 1.05 g of 6-chloro-1,3-dihydro-1-(2-piperidinoethyl)-2H-benzimidazol-2-one hydrochloride.
