Reaction Conditions

Reaction Steps

Sodium hydroxide in water (4 M solution, 1 ml, 4 mmol) was added into a solution of methyl 1-(4-fluorobenzyl)-3-(3-(2-methylpyridin-4-yl)-1H-indazole-5-carboxamido)cyclohexanecarboxylate (0.32 mmol) in methanol (0.5 ml) and THF (2 ml). The reaction solution was stirred at 70° C. for 16 h, and 1.0 N HCl solution was added dropwise to adjust pH to 4. The resulting solution was extracted with EtOAc (10 ml, twice). The combined organic layers were dried over sodium sulfate, filtered, concentrated, and purified using HPLC to give the titled compound. LC-MS: 487.21 [M+11]. LC/MS RT=2.36 min.
