Reaction Steps

To a solution of N-(5-(5-acetyl-1H-benzo[d]imidazol-1-yl)-2′,4′-difluoro-[1,1′-biphenyl]-3-yl)cyclopropanesulfonamide (110 mg, 0.235 mmol) in ethanol was added hydroxyl amine hydrochloride (24.7 mg, 0.353 mmol) and the mixture was heated at 80° C. for 2 h. The mixture was concentrated under vacuum and washed with ether to afford the product in 49% yield (55 mg). 1H NMR (400 MHz, DMSO-d6): δ 9.00 (s, 1H), 8.03 (s, 1H), 7.82-7.70 (m, 3H), 7.60-7.58 (d, 2H), 7.52 (s, 1H), 7.46-7.40 (m, 1H), 7.27-7.24 (m, 1H), 2.86-2.83 (m, 1H), 2.25 (s, 3H), 1.01-1.00 (m, 4H); LC-MS (ESI): Calculated mass: 482.5; Observed mass: 483.1 [M+H]+ (rt: 1.475 min).
