실험 절차

A solution of 3-cyclohexyl-imidazo[1,5-a]pyrazine 8a (960 mg, 4.4 mmol) in 25 ml ethanol was treated with 100 mg Adam's catalyst and stirred vigorously under one atmosphere of hydrogen for 18 hr. The mixture was filtered through a pad of Celite®. The filtrate was concentrated in vacuo to yield 790 mg of 3-cyclohexyl-5,6,7,8-tetrahydro-imidazo[1,5-a]pyrazine 9a as a greenish-yellow solid.
