Reaction Steps

20 ml of anisaldehyde, 50 ml of acetic anhydride, 33.7 g of hippuric acid and 6.7 g of sodium acetate were mixed well and heated on a water bath for 30 minutes. The precipitated crystals were washed with hot water and then filtered. They were then recrystallized from benzene and dried to obtain 40 g of 2-phenyl-4-(4-methoxybenzylidene)-5-oxazolone. Yield: 83%.
