実験手順

Example 8a (91 mg, 0.24 mmol) was reacted with 2-(bromomethyl)-pyridine hydrobromide (1.6 eq.) as described under General Procedure F and the crude mixture was purified by flash chromatography (silica gel, Et2O/hexane 1:1) to afford the title compound (55 mg, 49%) as a pale yellow oil. 1H NMR (300 MHz, CDCl3) δ 8.57 (m, 1H), 7.71 (dt, J=Hz, 1.8, 7.7 Hz, 1H), 7.42 (d, J=7.8 Hz, 1H), 7.24 (m, 1H), 7.11-7.06 (m, 2H), 6.94-6.88 (m, 2H), 5.17 (s, 2H), 3.95 (t, J=6.8 Hz, 2H) 3.86 (s, 3H), 2.93 (m, 1H), 2.45 (s, 3H), 2.20 (s, 3H), 1.97-1.91 (m, 2H), 1.20 (d, J=7.2 Hz, 3H). MS (ES+) m/z 472.2 (M+H+).
