実験手順
Sodium hydroxide (0.980 mL, 0.980 mmol) was added to a solution of methyl 1-(1-methylethyl)-6-(4-morpholinylsulfonyl)-1H-indazole-4-carboxylate (90 mg, 0.245 mmol) in ethanol (30 mL) and heated at reflux for 1 hour. The solvent was removed in vacuo and the residue suspended in water (20 mL). The contents were acidifed by addition of acetic acid, and extracted with DCM (4×30 mL). The combined organic layers were washed with water, brine, dried over MgSO4, filtered, and concentrated in vacuo. The product was collected as 90 mg. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.63-1.78 (m, 6H), 3.02-3.24 (m, 4H), 3.67-3.88 (m, 4H), 5.00 (dt, J=13.20, 6.66 Hz, 1H), 8.21 (s, 1H), 8.31 (s, 1H), 8.71 (s, 1H), LCMS(ES) [M+H]+ 354.2
