实验过程

N1-phenylbenzene-1,2-diamine (4.15 g, 22 mmol) and benzaldehyde (2.1 g, 20 mmol) were mixed with methoxylethanol (60 ml) in a three-neck flask. The mixture was heated up to reflux for 48 hours. After cooled to room temperature, the solvent was evaporated. The residue was purified by column chromatography using dichloromethane to 5% of ethyl acetate in dichloromethane as eluent. 2 g of desired product was obtained.
