実験手順

100 mg (0.211 mmol) of 2-[2-ethoxy-5-(4-methyl-piperazine-1-sulphonyl)-phenyl]-5-methyl-7-propyl-3H-imidazo[5,1-f][1,2,4]triazin-4-one are suspended in 5 ml of ether and admixed with 20 mg of an 85% strength solution of lactic acid in water. The mixture is stirred at room temperature for 10 minutes and evaporated to dryness. The residue is titrated with ether and filtered off with suction. This gives 110 mg (92%) of 2-[2-ethoxy-5-(4-methyl-piperazine-1-sulphonyl)-phenyl]-5-methyl-7-propyl-3H-imidazo[5,1-f][1,2,4]triazin-4-one lactate.
