実験手順

To a solution of 1-[(1S,2S)-2-(4-bromo-phenyl)-cyclopropylmethyl]-2(S)-methyl-pyrrolidine (the product of Example 1D, 50 mg, 0.17 mmol) in isopropyl alcohol (4 mL) under an atmosphere of nitrogen was added 4-cyanophenylboronic acid (30 mg, 0.2 mmol), dichlorobis(triphenylphosphine)palladium(II) (6 mg, 8.5 μmol) and potassium carbonate (59 mg, 0.43 mmol). The mixture was heated to 90° C. for 5 hours, cooled to ambient temperature and partitioned between ethyl acetate (25 mL) and H2O (10 mL). The separated organic layer was washed with brine, dried (MgSO4), filtered, concentrated under reduced pressure and chromatographed on silica gel eluting with 3% methanol (containing 10% concentrated NH4OH) in dichloromethane to provide the title compound. 1H NMR (300 MHz, CD3OD) δ 1.01 (m, 1H), 1.13 (m, 1H), 1.25 (d, J=6 Hz, 3H), 1.36 (m, 1H), 1.54 (m, 1H), 1.89 (m, 3H), 2.11 (m, 1H), 2.30 (m, 1H), 2.65 (m, 1H), 2.79 (m, 1H), 3.27 (dd, J=12 Hz, J=6 Hz, 1H), 3.40 (m, 1H), 7.22 (d, J=9 Hz, 2H), 7.59 (d, J=6 Hz, 2H), 7.78 (s, 4H). MS (DCl—NH3) m/z 317 (M+H)+.
