실험 절차
A solution of 2.01 g of 5-(p-formylphenyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyridine and 0.96 g of hydrazoic acid in 30 ml benzene is maintained by external cooling at room temperature, while 0.8 ml of concentrated sulfuric acid is added dropwise. The reaction mixture is stirred for 2 h and neutralized. The organic phase is separated, dried over sodium sulfate and evaporated to yield an oil which is chromatographed on silica gel with ethyl acetate to yield the title compound.
