Reaction Steps
50% Sodium hydride (2.4 g, 0.05 mol) was washed with petroleum ether, suspended in dry toluene (50 ml) and stirred at 5° C. Ethyl 3-(2-methoxyphenylamino)acrylate (8.7 g, 0.05 mol) in dry toluene (25 ml) was added and the mixture was stirred for 2.5 hours. Benzoyl chloride (6.8 g, 0.05 mol) in dry toluene (25 ml) was added dropwise and the mixture was heated under reflux for 2 hours. The mixture was cooled, washed with dilute hydrochloric acid, water and brine, then dried and evaporated. The residue was chromatographed (silica gel, dichloromethane) to afford ethyl 2-benzoyl-3-(2-methoxyphenylamino)acrylate (7.62 g, 46.8%) as a yellow oil.
