5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2(3H)-one → (E)-5-(8-Fluoro-10,11-dihydro-benzo[4,5]cyclohepta[1,2-b]pyridin-5-ylidenemethyl)-1,3-dihydro-benzoimidazol-2-one

Participants

Reaction Steps

Following procedures essentially as desctribed in Example 219, beginning with (E)-5-bromomethylene-8-fluoro-10,11-dihydro-benzo[4,5]cyclohepta[1,2-b]pyridine (100 mg, 0.33 mmol) and 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1,3-dihydro-benzoimidazol-2-one (111 mg, 0.43 mmol). After work-up, purify the crude product by flash chromatography (100% ethyl acetate to 10% ethanol/ethyl acetate) to provide 70 mg (60%) of purified product. LCMS (APCI-pos): 358.0 (M+H). LCMS (APCI-neg): 356.0 (M−H). Purity by LCMS (UV Area percent): 99%. 1HNMR (d6-DMSO, 400 MHz): δ10.56 (s, 1H), 10/46 (s, 1H), 8.38 (dd, 1H), 7.88 (dd, 1H), 7.28 (dd, 1H), 7.23 (dd, 1H), 6.96-6.90 (m, 2H), 6.89 (s, 1H), 6.73 (d, 1H), 6.68 (d, 1H), 6.52 (s, 1H), 3.5-3.3 (m, 2H), 3.1-2.9 (m, 2H).
