실험 절차

To a mixture of 2-bromoaniline (0.976 g, 5.81 mmol, Sigma-Aldrich) and K2CO3 (1.16 g, 8.71 mmol) in water (5.5 mL) and acetone (4.5 mL) was added cinnamoyl chloride (1 g, 5.81 mmol, Sigma-Aldrich) and the reaction was stirred for 2 h at 0° C. The mixture was treated with ice cold water (25 mL) to obtain a brownish precipitate. The precipitate was filtered and dried under vacuum. The crude material was further treated with petroleum ether to give N-(2-bromophenyl)cinnamamide (1.1 g, 64%) as off-white solid. MS (ESI, pos. ion) m/z: 303.2 (M+1).
