N-Methylhomoveratrylamine → N-[2-(3,4-Dimethoxy-phenyl)-ethyl]-4-ethoxy-N-methyl-3-(6-methyl-4-oxo-8-propyl-3,4-dihydro-imidazo[1,5-a][1,3,5]triazin-2-yl)-benzenesulfonamide

참여 물질

반응 단계

143 mg (0.73 mmol) of N-(3,4-dimethoxyphenylethyl)-N-methylamine 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), 138 mg (98%) of N-[2-(3,4-dimethoxy-phenyl)-ethyl]-4-ethoxy-N-methyl-3-(6-methyl-4-oxo-8-propyl-3,4-dihydro-imidazo[1,5-a][1,3,5]triazin-2-yl)-benzene-sulfonamide are obtained.
