To a hot solution of 6.0 g. (21.2 mmoles) of 2-[2-(2-chlorobenzoyl)phenyl]-2-imidazoline in 25 ml. of 6 N methanolic hydrogen chloride and 35 ml. of methanol was added 200 ml. of ether and the solution cooled. Filtration gave 2-[2-(2-chlorobenzoyl)phenyl]-2-imidazoline hydrochloride, m.p. 178°-180° dec. Dilution of the mother liquors with 200 ml. of ether followed by cooling and filtering afforded an additional quantity of hydrochloride. Recrystallization from methanol-ether gave colorless prisms, m.p. 178°-180° dec.
