실험 절차

A 4N-hydrochloric acid/dioxane solution (2.0 ml) was added to tert-butyl 4{[(1H-indazol-5-ylmethyl)amino]carbonyl}-1-piperidinecarboxylate (160 mg, 0.446 mmol), and the resulting mixture was stirred at room temperature for 2 hours. Then, the reaction solution was poured into a saturated aqueous sodium hydrogencarbonate solution and extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate and distilled under reduced pressure to remove the solvent. The resulting residue was recrystallized from a mixture of ethanol and diethyl ether to obtain N-(1H-indazol-5-ylmethyl)-4-piperidinecarboxamide (10 mg, 9%).
