반응 단계

n-Butylamine (8.31 ml, 84.1 mmol) and methyl 4-formylbenzoate (10.6 g, 64.7 mmol) was heated with reflux benzene (50 ml) in a Dean-Stark trap until a theoretical amount of water was recovered. The solvent was evaporated under reduced pressure. To the residue were added glacial acetic acid (30 ml) and nitrobutane (10.0 g, 97.0 mmol), and the mixture was stirred at 110° C. for 4 hrs. and allowed to cool to room temperature. The insoluble materials were filtered off and dried to give the title compound (7.53 g) as a pale-yellow powder.
