反応手順

A solution of 1.65 g of 5-(p-cyanophenyl)-5-ethoxycarbonyl-5,6,7,8-tetrahydroimidazo[1,5-a]pyridine in 10 ml of methanol containing 0.2 g of sodium hydroxide is stirred for 3 h at room temperature and 5 ml of 1N hydrochloric acid is added. The reaction mixture is refluxed for 1 h, cooled and evaporated. The residue is partitioned between water and ethyl acetate. The organic layer is separated, dried over sodium sulfate and evaporated to yield the title compound.
