실험 절차

A suspension of 26 g of 5-(5-ethoxycarbonylpentyl)imidazo[1,5-a]pyridine in 100 ml of 1N aqueous sodium hydroxide solution is heated on a steam bath for two hours; 10 ml of ethanol is added and heating is continued for 45 minutes. The reaction mixture is cooled, washed with 300 ml of ether and the solution is adjusted to pH 5.5 with concentrated hydrochloric acid. The crystallized product is collected to yield 5-(5-carboxypentyl)-imidazo[1,5-a]pyridine melting at 144°-147°.
