To 3,3-bis(4-fluorophenyl)-1-(2-oxo-2-(2,7-diazaspiro[3.5]nonan-2-yl)ethyl)pyrrolidin-2-one (0.050 g, 0.114 mmol; Example 153A) and 1-(bromomethyl)-4-(trifluoromethyl)benzene (0.030 g, 0.125 mmol) in dichloromethane (0.5 mL) was added N-ethyl-N-isopropylpropan-2-amine (0.030 mL, 0.171 mmol), and the reaction was heated to 40° C. for 1 hour. The reaction was cooled, loaded onto a GraceResolv™ 12 g silica gel column (Grace Davison Discovery Sciences), and the title compound eluted with a gradient of 0.8% methanol/dichloromethane containing 0.2 N NH3 to 5.6% methanol/dichloromethane containing 0.2 N NH3(Flow=25 mL/minute) over 30 minutes. 1H NMR (300 MHz, CDCl3) δ 7.57 (d, J=8.1, 2H), 7.42 (d, J=8.0, 2H), 7.34-7.27 (m, 4H), 7.04-6.94 (m, 4H), 3.97 (s, 2H), 3.72 (d, J=19.3, 4H), 3.52 (dd, J=5.5, 12.0, 4H), 2.75 (t, J=6.5, 2H), 2.31 (s, 4H), 1.74 (d, J=4.9, 4H); MS (ESI+) m/z 598.2 (M+H)+.
