実験手順
[(2S)-2-(4-Fluorophenyl)pent-4-en-1-yl]methylamine (see Bioorg. Med. Chem. Lett; 2001; 265-270; 150 mg, 0.78 mmol) was dissolved in CH2Cl2 (5 mL) and to the resultant solution were added DIPEA (221 mg, 1.71 mmol) and 3,5-dichlorobenzoyl chloride (178 mg, 0.85 mmol) in the given order. The mixture was stirred for 4 h at room temperature, diluted with CH2Cl2 (20 mL), and then washed with water (10 mL), aqueous KHSO4 (1M, 10 mL) and brine (10 mL). The organic solution was dried over Na2SO4. The solvent was removed by evaporation and there was obtained 214 mg (75%) of 3,5-dichloro-N-[(2S)-2-(4fluorophenyl)pent-4-en-1-yl]-N-methylbenzamide as an oil. 1H NMR (500 MHz, CDCl3): 2.2-2.4 (cm, 2H), 2.6 (s, 2H), 2.9-3.9 (cm, 4H), 4.9-5.1 (m, 2H), 5.5-5.8 (m, 1H), 6.7 (s, 1H), 6.9-7.4 (cm, 6H); LCMS: m/z 367 (M+1)+.
