5-[p-(2-Ethoxycarbonylprop-1-enyl)phenethyl]imidazo[1,5-a]pyridine (0.33 g) in 10 ml of 0.5N sodium hydroxide is refluxed for 3 hours, cooled and extracted with ether. The aqueous phase is adjusted to pH=6 and the resulting solid is filtered off to yield 5-[p-(2-carboxyprop-1-enyl)phenethyl]imidazo[1,5-a]pyridine.
