Reaction Steps

To a suspension of 8-bromo-N-(2-chlorophenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide 150 (100 mg, 0.22 mmol), Cs2CO3 (158 mg), acetamide (20 mg), and xantphos (13 mg) in dry 1,4-dioxane (2 mL) was degassed with bubbling N2. Pd2 dba3 was added and the 10 mL tube was sealed and heated at 110° C. for 8 hr. After cooling to room temp., the mixture was diluted with water and extracted with ethylacetate. The combined organics were concentrated and the crude residue obtained purified by reverse phase HPLC to give 151. 1H NMR (500 MHz, DMSO-d6) δ 10.03 (s, 1H), 7.65 (m, 2H), 7.62 (m, 2H), 7.35 (m, 2H), 7.17 (m, 1H), 6.51 (br s, 1H), 4.15 (m, 2H), 3.29 (s, 3H), 2.91 (m, 2H), 2.03 (s, 3H) MS: (ESI+) 427.1
