Reaction Steps

A solution of 2-[N-(1-acetyl-3-phenyl-1H-indazole-5-yl)carbamoyl]phenyl acetate (100 mg, 0.241 mmol) in methanol (11 mL) with 0.3% ammonia was allowed to stir for three hours at reflux temperature. The mixture was then acidified with 5% HCl solution until neutral pH. The resulting solid was filtered, dried and triturated with hexanes to give the title compound (45 mg, 57% yield). 1H NMR (DMSO-d6) δ 13.23 (br s, 1H), 11.92 (br s, 1H), 10.47 (s, 1H), 8.45 (s, 1H), 7.96 (m, 3H), 7.51 (m, 6H), 6.95 (d, 2H); ES-MS (m/z) 330 [M+1]+.
