Procedure

Combine 4-(5-formyl-pyridin-2-yloxy)-benzamide (100 mg, 0.413 mmol), (±)-3-phenyl-pyrrolidine (78 mg, 0.318 mmol), sodium triacetoxy-borohydride (101 mg, 0.477 mmol), AcOH (0.018 mL, 0.318 mmol) in CH2Cl2 (5 mL). Stir at rt overnight. Pour the reaction mixture onto an SCX column, eluting with ammonia (2M in methanol) followed by chromatography [CH2Cl2:ammonia (2.0 M in methanol) 20:1] to provide the title compound (43 mg, 36%). Mass spectrum (ion spray): m/z=373.9 (M+1); 1H NMR (DMSO-d6): 8.09 (d, J=1.9 Hz, 1H), 7.93 (bs, 1H), 7.89 (d, J=8.6 Hz, 2H), 7.82 (dd, J=2.2 Hz, 8.6 Hz, 1H), 7.30 (bs, 1H), 7.27-7.24 (m, 4H), 7.17-7.12 (m, 3H), 7.03 (d, J=8.3 Hz, 1H), 3.61 (dd, J=13.1 Hz, 19.5 Hz, 2H), 3.33-3.24 (m, 1H), 2.88 (t, J=8.3 Hz, 1H), 2.66 (t, J=7.0 Hz, 2H), 2.42 (t, J=8.3 Hz, 1H), 2.28-2.18 (m, 1H), 1.79-1.70 (m, 1H).
