Using a method similar to Example 365 step 2, using 3-phenyl-pyrollidine (0.169 g, 1.15 mmol), 6-(4-formyl-2-fluoro-phenoxy)-nicotinonitrile (compound of example 375 step 1), (0.200 g, 0.826 mmol), sodium triacetoxyborohydride (0.262 g, 1.24 mmol), and acetic acid (0.071 mL, 1.24 mmol) in 1,2-dichloroethane (8.0 mL), after silica gel chromatography (3:1 hexanes:ethyl acetate), provides 0.231 g (75%) of the title compound as a clear syrup: mass spectrum (electrospray): m/z=374.2 (M+1); 1H NMR (CDCl3): 8.40 (d, 1H, J=2.9 Hz), 7.91 (dd, 1H, J=2.4, 8.3 Hz), 7.30-7.24 (m, 2H), 7.24-7.21 (m, 3H), 7.20-7.09 (m, 3H), 7.06 (d, 1H, J=8.8 Hz), 3.70-3.61 (m, 2H), 3.40-3.31 (m, 1H), 3.01 (t, 1H, J=8.8 Hz), 2.84-2.77 (m, 1H), 2.75-2.67 (m, 1H), 2.53 (dd, 1H, J=7.8, 9.3 Hz), 2.39-2.28 (m, 1H), 1.95-1.84 (m, 1H).
