実験手順

83 mg (0.73 mmol) of N-ethylpiperazine are added to a solution of 100 mg (0.24 mmol) of 4-ethoxy-3-(6-methyl-4-oxo-8-propyl-3,4-dihydro-imidazo[1,5-a]-[1,3,5]triazin-2-yl)-benzenesulfonyl chloride (example VI) in 5 ml of dichloromethane and the reaction mixture is stirred at room temperature for 2 hours. After chromatographic purification (dichloromethane/methanol=95:5), 104 mg (87%) of 2-[2-ethoxy-5-(4-ethyl-piperazine-1-sulfonyl)-phenyl]-6-methyl-8-propyl-3H-imidazo[1,5-a][1,3,5]triazin-4-one are obtained.
