実験手順
5-[2-(p-[Ethoxycarbonylmethoxy]phenyl)-ethen-1-yl]imidazo[1,5-a]pyridine (3.2 g) is refluxed in 30 ml of ethanol with 20 ml of 1N sodium hydroxide for 3 hours. The ethanol is evaporated and the aqueous phase is adjusted to pH=6. Filtration yields the substituted phenoxyacetic acid 5-[2-(p-carboxymethoxy]phenyl)ethen-1-yl]imidazo[1,5-a]pyridine.
