Reaction Conditions

Reaction Steps

A mixture of 3-(2,3-dihydrobenzo[b]furan-5-yl)-1H-indazole-5-carbonitrile (0.50 g, 1.9 mmol), 95% ethanol (6 mL), aqueous 30% hydrogen peroxide (3 mL), and 6.0 N aqueous sodium hydroxide (1 mL) was heated at 45° C. for 3 h. The reaction mixture was diluted with water (40 mL) and acidified to pH 6 with 3 N hydrochloric acid. The solid was filtered and dried in a vacuum oven to give product (0.080 g, 53% yield): 1H NMR (DMSO-d6) δ 13.22 (s, 1H), 8.54 (s, 1H), 8.12 (s, 1H), 7.90 (d, 2H), 7.76 (d, 1H), 7.55 (d, 1H), 7.32 (s, 1H), 6.91 (d, 1H), 4.59 (t, 2H), 3.28 (t, 2H); ES-MS (m/z) 280 [M+1]+.
