実験手順
8-(4-Phenyl-1H-imidazol-2-yl)-3-(prop-2-ynyl)imidazo[5,1-d][1,2,3,5]tetrazin-4(3H)-one (1.07 mmol) was dissolved in dry DMF (35 mL) and cooled in ice under a nitrogen atmosphere. A 60% suspension of sodium hydride in mineral oil (1.18 mmol) was added in one portion and the reaction stirred on ice for 10 minutes. Methyl iodide (2.14 mmol) was then added dropwise to the reaction and the mixture stirred at room temperature for 48 hours. The mixture was poured onto ice water (140 mL) and the precipitate was filtered, washed with water, ethyl acetate, and diethyl ether, and purified by column chromatography (hexane:ethyl acetate 4:3) to give the title compound (0.030 g; 89%). δH (DMSO-d6) 8.97 (1H, s), 7.90 (1H, s), 7.83 (2H, d, J=7.2), 7.40 (2H, t, J=7.6), 7.25 (1H, t, J=7.2), 5.13 (2H, d, J=2.0), 3.99 (3H, s), 3.52 (1H, J=2.0).
