실험 절차

A solution of acetic anhydride (0.55 cm3) in dichloromethane (20 cm3) was added dropwise to a stirred solution of 6-amino-2-methoxy-8-methylquinoline (1.0 g) in dichloromethane (30 cm3) at room temperature. After 1 hour the solution was diluted with dichloromethane (50 cm3), washed with saturated sodium carbonate solution (10 cm3), and dried (MgSO4). Evaporation of the solution in vacuo afforded a solid which was recrystallised from dichloromethane/hexane to give 6-acetamido-2-methoxy-8-methylquinoline, m.p. 193°-196° (1.143 g).
