실험 절차

Compound 13 (237 mg, 0.584 mmol) was dissolved in isobutyl alcohol (1.2 mL), and the solution was stirred overnight under heat and reflux after adding a 5 mol/L sodium hydroxide aqueous solution (1.2 mL). The reaction mixture was stirred after adding diethyl ether, and the aqueous layer was removed. Then, 3 mol/L hydrochloric acid (2.0 mL) was added to the aqueous layer, and the mixture was stirred. The precipitated crystals were collected by filteration to give 3-cyclohexylsulfonyl-2-isopropylimidazo[1,2-a]pyridine-7-carboxylic acid (86.2 mg, yield 42%).
