実験手順

A stirred mixture of 5-cyclopropyl-2-(4-fluorophenyl)-N-methyl-6-(methylsulfonamido)benzofuran-3-carboxamide (0.500 g, 1.24 mmol), (4-(benzyloxy)phenyl)boronic acid (0.567 g, 2.49 mmol), copper(II) acetate (0.451 g, 2.49 mmol), and triethylamine (1.00 mL, 7.12 mmol) in DCM (25 mL) was treated with 1.00 g of powdered 3 angstrom molecular sieves. The resulting mixture was stirred at RT under air using a drying tube to exclude moisture. After 18 hours the mixture was treated with an additional 250 mg portion of (4-(benzyloxy)phenyl)boronic acid and stirring at RT continued. After another 8 hours the mixture was filtered through Celite and the filtrate concentrated to dryness at reduced pressure. The black residue was suspended in EtOAc and the undissolved solids removed by filtration through Celite. The filtrate was concentrated to dryness at reduced pressure and the residue subjected to flash chromatography (silica gel, gradient elution from DCM to 1:1 DCM/EtOAc to give the title compound (0.403 g, 56%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.39-8.47 (m, 1H) 8.12-8.18 (m, 1H) 7.92-7.99 (m, 2H) 7.55 (d, J=8.9 Hz, 2H) 7.28-7.46 (m, 7H) 7.13 (s, 1H) 7.03 (d, J=9.0 Hz, 2H) 5.09 (s, 2H) 3.29 (s, 3H) 2.82 (d, J=4.5 Hz, 3H) 2.25-2.35 (m, 1H) 0.75-1.14 (m, 3H) 0.32-0.58 (m, 1H).
