Reaction Steps
1.8 g of hippuric acid and 0.4 g of potassium bicarbonate are dissolved in 4 ml of acetic anhydride, the solution is heated for a few minutes at 50° C. and then cooled to room temperature and 1.49 g of benzaldehyde are added. After 1 hour at room temperature, 20 ml of distilled water are added at 80° C. The solid which precipitates is filtered off, washed with water and ethanol and then dried to give 1.24 g of the expected product in the form of a yellow solid.
