実験手順
A (1:3) mixture of 1-[4-(3-bromo-propoxy)-phenyl]-cyclohexanecarbonitrile and 1-[4-(3-chloro-propoxy)-phenyl]-cyclohexanecarbonitrile (2.00 g, 7.20 mmol), Cs2CO3 (2.58 g, 7.20 mmol), potassium iodide (0.20 g, 1.20 mmol) and (R)-(−)-2-(methoxymethyl)pyrrolidine (1.07 mL, 8.60 mmol) in NMP (20 mL) was heated to 75° C. overnight. The reaction mixture was cooled to ambient temperature, concentrated in vacuo, and quenched by adding water (30 mL). The crude product was extracted with ethyl acetate (30×mL) and the organic extracts were dried over Na2SO4, filtered and concentrated in vacuo. The compound was purified by column chromatography on Biotage® silica gel, eluting with dichloromethane:methanol:ammonia, 100:0:0 to 90:10:1 to give the title compound as a brown oil (1.39 g, 54%). 1H NMR (400 MHz, CDCl3) δ 7.38 (d, 2H), 6.70 (d, 2H), 4.02 (t, 2H), 3.46-3.38 (m, 1H), 3.36-3.28 (m, 3H), 3.24-3.16 (m, 1H), 3.12-3.04 (m, 1H), 2.72-2.58 (m, 1H), 2.52-2.44 (m, 1H), 2.30-2.20 (m, 1H), 2.18-2.06 (m, 2H), 1.98 (pentet, 2H), 1.92-1.60 (m, 12H), 1.36-1.18 (m, 1H); HRMS (ESI+) 357.2537 (M+H)+.
