Procedure
A 20% sodium hydroxide solution (10 ml.) is added to a stirred solution of p-chlorobenzaldehyde (19.4 g., 0.138 mole) and 3,4-diphenyl-2-butanone (31.06 g., 0.138 mole) in ethanol (400 ml.). The cream-colored solid that separates is collected, washed with water, and dried at 90°C., yield 41.13 g., m.p. 113°-115°C. Recrystallization from ethanol gives material with m.p. 117°-118.5 C.
