Reaction Steps

Following procedures essentially as described in Example 219, mix 11-bromomethylene-3,7-difluoro-6,11-dihydro-dibenzo[b,e]oxepine (E-isomer, 68 mg, 0.21 mmol), 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1,3-dihydro-benzoimidazol-2-one (52 mg, 0.20 mmol), Na2CO3 (2M in water, 251 μL, 0.503 mmol), dioxane (2 mL), and Pd(PPh3)4 (12 mg, 0.010 mmol). Purify on silica gel (12 g) eluting with THF to afford a brown solid. Triturate with acetone to afford 56 mg (74%) of the title compound as a white solid. HPLC (ISO80-10) t=2.42 min, 96%; MS [ES] 375 (M−H); 1H-NMR (DMSO-d6) δ 10.58 (s, 1H), 10.46 (s, 1H), 7.57 (dd, 1H, J=8.8, 7.0 Hz), 7.24 (m, 2H), 7.00 (s, 1H), 6.81 (m, 2H), 6.72 (m, 2H), 6.64 (dd, 1H, J=10.6, 2.6 Hz), 6.59 (s, 1H), 5.55-5.19 (br d, 2H).
