実験手順

A solution of 6-(N-(4-(benzyloxy)phenyl)methylsulfonamido)-5-cyclopropyl-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (0.174 g, 0.298 mmol) in 3:1 THF/EtOH (20 mL) was subjected to hydrogenation at 40 psi in the presence of 5% palladium on charcoal (20 mg). After 3 hours the reaction vessel was purged with nitrogen, catalyst removed by filtration through Celite and the filtrate concentrated to dryness at reduced pressure. The residue was triturated with DCM/hexane. The resulting solid was collected by filtration and dried in vacuo to afford the title compound (144 mg, 98%) as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 9.67 (br. s., 1H) 8.44 (q, J=4.4 Hz, 1H) 8.13 (s, 1H) 7.97 (dd, J=8.9, 5.4 Hz, 2H) 7.46 (d, J=8.9 Hz, 2H) 7.40 (t, J=8.9 Hz, 2H) 7.12 (s, 1H) 6.77 (d, J=8.9 Hz, 2H) 3.27 (s, 3H) 2.83 (d, J=4.6 Hz, 3H) 2.28-2.39 (m, 1H) 0.76-1.11 (m, 3H) 0.47 (br. s., 1H). LCMS (m/z, ES+)=495 (M+H+).
