Reaktionsschritte

Example 8a (89 mg, 0.18 mmol) was reacted with 4-fluoropiperidine hydrochloride (4.0 eq.) as described under General Procedure J and the crude mixture was purified by flash chromatography (silica gel, Et2O/hexane 3:2) to afford the title compound (38 mg, 41%) as a pale yellow oil. 1H NMR (300 MHz, CDCl3) δ 7.20-7.15 (m, 2H), 7.01-6.95 (m, 2H), 4.66 (m, 1H), 4.05 (t, J=5.9 Hz, 2H), 3.95 (t, J=6.6 Hz, 2H), 3.83 (s, 3H), 3.00 (m, 1H), 2.64-2.59 (m, 4H), 2.50 (s, 3H), 2.44-2.36 (m, 2H), 2.18 (s, 3H), 2.05-1.97 (m, 2H), 1.94-1.81 (m, 4H), 1.30 (d, J=6.9 Hz, 3H).
