반응 단계

1-(3-Aminopropyl)imidazole (2.39 ml, 0.02 mol) was added to a solution of 4-bromobenzoyl chloride (4.0 g, 0.018 mol) in ethanol (250 ml). The mixture was stirred at ambient temperature for 18 hours. The volatiles were removed by evaporation and the residue was purified by chromatography eluting with hexane/dichloromethane (50:50) increasing in polarity to dichloromethane/methanol (80:20) to give the title compound. NMR: 1.95 (m, 2H), 3.20 (q, 2H), 4.0 (t, 2H), 6.87 (s, 1H), 7.19 (s, 1H), 7.64 (d, 2H), 7.68 (s, 1H), 7.78 (d, 2H), 8.58 (t, 1H); m/z: 308 [MH]+.
