Reaction Steps
Benzanilide is prepared by the method of Example 5 using 5.0 mls (0.05 mole) of aniline, 7.5 grams of 3A molecular sieves and 7.48 mls (0.064 mole) of benzoyl chloride in 100 mls of dichloromethane. The separated 3A sieves (16.37 g) are extracted with 200 mls of hot 3A alcohol, and the alcohol extract is evaporated to dryness to obtain 7.24 grams (68% of theoretical) of crude benzanilide; m.p. 161°-163° C. after recrystallization from 3A alcohol. Dichloromethane filtrates from above reaction are evaporated to dryness and extracted with ethyl ether to obtain an additional 1.39 grams of crude benzanilide.
