PROCEDURE
实验过程
Following procedures essentially as described in Example 219, mix 1-(2-morpholin-4-yl-ethyl)-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1,3-dihydro-benzoimidazol-2-one (300 mg, 1.03 mmol), 11-bromomethylene-3-fluoro-6,11-dihydro-dibenzo[b,e]oxepine (E isomer, 330 mg, 1.08 mmol), 2N Na2CO3 (1.4 mL), dioxane (10 mL) and (Ph3P)4Pd (44 mg, 0.038 mmol). Purify the crude product by column chromatography using 40% THF/hexane to yield 80 mg title compound as a pale yellow powder. HPLC (ISO80-10M) t=1.84 (96%), MS (ES) 472 (M+1), 470 (M−1). H NMR (DMSO-d6)10.72 (s, 1H), 7.57 (m, 2H), 7.35 (t, 1H, J=7.5 Hz), 7.23 (t, 1H, J=7.5 Hz), 7.00 (d, 1H, J=7.5 Hz), 6.97 (s, 1H), 6.93 (d, 1H, J=8.4 Hz), 6.79 (td, 1H, J=11.9, 4.3 Hz), 6.73 (d, 1H, J=8.4 Hz), 6.60 (m, 2H), 5.82-4.79 (m, 2H), 3.80 (t, 2H, J=6.4 Hz), 3.46 (t, 4H, J=4.4 Hz), 2.48 (m, 2H), 2.38 (s, 4H).
