実験手順: (4-Bromophenylamino)acetic acid, methyl ester (8.74 g, 0.036 mol) was treated with cinnamoyl chloride (11.99 g, 0.072 mol) in pyridine (50 mL) in the presence of 4-dimethylaminopyridine (0.489 g, 0.004 mol). The reaction mixture was stirred at room temperature for 2 h. The crude product was purified by flash column chromatography on silica gel, eluting with ethyl acetate/dichloromethane (1:20), to give the title compound as a white crystalline solid (13.13 g, 98%). 1HNMR (300 MHz) (CDCl3) δ 3.67 (3H, s), 4.42 (2H, s), 6.28 (1H, d, J=16 Hz), 7.19 (2H, d), 7.2-7.3 (5H, m), 7.51 (2H, d) and 7.66 (1H, d, J=16 Hz).

実験手順: Potassium carbonate (2.41 g, 17.4 mmol) is added to a stirred solution of 4-bromo-aniline (2.00 g, 11.6 mmol) and methyl bromoacetate (1.78 g, 11.6 mmol) in dry DMF (20 mL) at ambient temperature. The mixture is heated at 100° C. for 1 hour. At ambient temperature ethyl acetate (60 mL) and water (60 mL) are added to the mixture. The organic layer is separated, washed with half-saturated brine, dried, filtered and concentrated. After MPLC separation on silica (gradient 0-15% ethyl acetate in hexane), 0.94 g (33% yield) of the title compound is obtained. 1H NMR (DMSO-d6): δ3.62 (s, 3H), 3.87 (d, J=6.4 Hz, 2H), 6.22 (t, J=6.4 Hz, 1H), 6.49 (d, J=8.8 Hz, 2H), 7.19 (d, J=8.8 Hz, 2H). The organic layer is separated washed with half-saturated brine dried filtered concentrated After MPLC separation on silica (gradient 0-15% ethyl acetate in hexane)
