2.1 g (19.3 mmol) of 4-aminophenol was dissolved in 28 ml ethanol, and 1.9 ml (19.3 mmol) benzaldehyde was added. The mixture was heated to the reflux temperature and reacted for 1.5 h, Then, the reaction mixture was cooled to the room temperature and the solid separated out from the mixture was filtered by sucking. The filter cake was washed with a small amount of ethanol and dried to obtain 3 g of a yellow solid with the yield of 76.9%. m.p. 182-183° C.
