実験手順

A suspension of 6-methyl-1-[(4-methylphenyl)sulfonyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,6-dihydro-7H-pyrrolo[2,3-c]pyridin-7-one (85.0 mg, 0.20 mmol), 5-bromo-6-(2,4-difluorophenoxy)-1,3-dihydro-2H-benzimidazol-2-one (74.5 mg, 0.218 mmol), potassium phosphate (0.10 g, 0.50 mmol), tris(dibenzylideneacetone)dipalladium (O) (5.0 mg, 0.006 mmol), and 1,3,5,7-tetramethyl-8-phenyl-2,4,6-trioxa-8-phosphatricyclo[3.3.1.13,7]decane (6.8 g, 0.0232 mmol) in 1,4-dioxane (2 mL) and water (0.4 mL) was degassed with nitrogen for 5 min and stirred at 80° C. for 1 h. The reaction mixture was diluted with ethyl acetate and water and filtered over celite. The organic layer was separated, washed with brine, dried with magnesium sulfate, filtered, and concentrated to give a crude residue. Purification via preparative LCMS (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% trifluoroacetic acid, at flow rate of 60 mL/min) gave the desired product (24 mg, 18%) as an off-white foam. LCMS calculated for C28H21F2N4O5S (M+H)+: m/z=563.1. found: 563.1.
