A solution of 5-(p-ethoxycarbonylphenyl)-imidazo[1,5-a]pyridine (1.0 g) in 10 ml of ethanol and 10 ml of 1N sodium hydroxide is refluxed for 3 hours. The ethanol is evaporated. The aqueous phase is washed with ether, adjusted to pH=6 and the solid collected to yield 5-(p-carboxyphenyl)imidazo[1,5-a]pyridine.
