Participants

Reaction Steps

Triethylamine (0.43 ml) was added to a solution of 2-acetyl-7-methoxy-4-benzofuransulphonyl chloride (600 mg) and 3-(aminomethyl)pyridine (0.25 ml) in dichloromethane at room temperature. The resultant mixture was stirred for 20 hours and then diluted with dichloromethane (20 ml). The solution was washed with water (20 ml) and brine (20 ml) and dried (MgSO4). Concentration in vacuo provided a dark oil which was applied to a silica column and eluted with 2% methanol in dichloromethane. The title compound was obtained as a pale yellow solid (161 mg).
