실험 절차

A solution of N-(benzyloxy)-3-methyl-4-oxo-3,4-dihydroimidazo[5,1-d][1,2,3,5]tetrazine-8-carboxamide (200 mg, 0.67 mmol) and 10% Pd/C (20 mg) in ethyl acetate:DMF (5:1) (36 mL) was put under an atmosphere of hydrogen for 3 days. The mixture was filtered through a pad of Celite™ and the filtrate was concentrated under vacuum. The residue was suspended in ethyl acetate and the precipitate was filtered and washed successively with water, ethyl acetate and diethyl ether to give the pure title compound as a pale orange solid (35 mg, 25% yield). δH (DMSO-d6): 11.2 (1H, s), 9.18 (1H, s), 8.82 (1H, s), 3.86 (3H, s).
