Reaction Steps

Ethyl 4-(4-chlorobenzylamino)-benzoate (11.56 g; 0.04 M), acetic anhydride (40 ml) and concentrated sulphuric acid (5 drops) were mixed and heated with stirring on a steam-bath for 1 hour. The mixture was cooled to room temperature, added to iced water (100 ml) and neutralised with solid sodium bicarbonate. The product was extracted into dichloromethane (2×100 ml), washed with water (1×100 ml) and evaporated to give an oil from which N-(4-ethoxycarbonylphenyl)-N-(4-chlorobenzyl)-acetamide (8.32 g; 63%) was obtained by chromatography on silica-gel in dichloromethane then 2% methanol-dichloromethane followed by crystallisation from ethanol. M.p. 65°-6° C.
