(2S)-N-Ethyl-2-(4-fluorophenyl)pent-4-en-1-amine (0.13 g, 0.63 mmol) was dissolved in CH2Cl2 and to the solution were added DIPEA (0.18 g, 1.4 mmol) and then 3-cyano-5,6,7,8-tetrahydronaphthalene-1-carbonyl chloride (see WO 00/34243; 0.15 g, 0.66 mmol) dissolved in CH2Cl2 (2 mL). The mixture was stirred for 2 h at room temperature and then diluted with CH2Cl2. The solution was washed with water, aqueous KHSO4 (10 mL, 1M) and brine. The solvent was removed by evaporation after the solution had been dried. The product was purified by chromatagraphy on silica gel using a gradient of methanol-CH2Cl2 (0% methanol-5% methanol). There was obtained 0.13 g (53%) of 3-cyano-N-ethyl-N-[(2S)-2-(4-fluorophenyl)pent-4-en-1-yl]-5,6,7,8-tetrahydronaphthalene-1-carboxamide as an oil.
