Participants

Reaction Steps

The title compound was prepared using the procedure described in Example 172 substituting 2-(2-oxo-3,3-diphenylpiperidin-1-yl)acetic acid from Example 68E for 2-(3,3-bis(4-fluorophenyl)-2-oxopiperidin-1-yl)acetic acid and 3,3-bis(4-fluorophenyl)pyrrolidine from Example 203A for 3,3-diphenylpyrrolidine. 1H NMR (300 MHz, CDCl3) δ ppm 7.30 (d, J=4.4, 8H), 7.25-7.21 (m, 2H), 7.17-7.10 (m, 4H), 6.98-6.88 (m, 4H), 4.14-4.07 (m, 4H), 3.67-3.45 (m, 4H), 2.70-2.60 (m, 2H), 2.55 (t, J=6.7, 1H), 2.45 (t, J=6.8, 1H), 1.90-1.78 (m, 2H); MS (DCI) m/z 551.2 (M+H)+.
