A mixture of 5-cyclopropyl-2-(4-fluorophenyl)-6-(N-(4-hydroxyphenyl)methylsulfonamido)-N-methylbenzofuran-3-carboxamide (85.0 mg, 0.172 mmol), potassium carbonate (0.119 g, 0.859 mmol), and 2-(bromomethyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.152 g, 0.688 mmol) in MeCN (3 mL) in a sealed tube was heated to 65° C. with stirring. After 2 hours the mixture was cooled to RT, filtered to remove solids, and the filtrate concentrated to dryness at reduced pressure. The residue was subjected to RP-HPLC purification (C18, MeCN/water/0.1% formic acid) followed by lyophilization from MeCN/water to give the title compound (77 mg, 81%) as a white powder. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.40-8.47 (m, 1H) 8.15 (s, 1H) 8.03 (s, 2H) 7.97 (dd, J=8.8, 5.4 Hz, 2H) 7.53 (d, J=9.0 Hz, 2H) 7.40 (t, J=8.9 Hz, 2H) 7.12 (s, 1H) 6.90 (d, J=9.1 Hz, 2H) 3.58 (s, 2H) 3.33 (s, 3H) 2.82 (d, J=4.5 Hz, 3H) 2.24-2.38 (m, 1H) 0.76-1.10 (m, 3H) 0.47 (br. s., 1H).
