Procedure

Example 34b (58 mg, 0.13 mmol) and 3,3-difluoropyrrolidine hydrochloride (2.5 eq.) were reacted as described under General Procedure J and the crude product was purified by flash chromatography (silica gel, hexane/Et2O 70:30) to afford the title compound as a pale yellow oil (10 mg, 16%). 1H NMR (300 MHz, CDCl3) δ 7.33-7.18 (m, 5H), 4.08 (t, J=6.2 Hz, 4H), 3.88 (s, 3H), 2.96 (t, J=13.4 Hz, 2H), 2.85-2.73 (m, 6H), 2.51 (s, 3H), 2.31-2.13 (m, 2H), 2.20-2.04 (m, 2H). MS (ES+) m/z 482.1 (M+H+).
