실험 절차

1-(1-Ethylpropyl)-4-oxo-4,5-dihydroimidazo[1,5-a]quinoxaline-7-carboxyic acid as synthesized in above Example 13, 300 mg was dissolved in 10 mL of N,N-dimethylformamide, and to the solution 1,1′-carbonyldiimidazole 275 mg was added little by little in nitrogen atmosphere. After another hour's stirring, ammonia gas was injected into the reaction liquid for 30 minutes, followed by an hour's stirring. Water 30 mL was added and the formed precipitate was recovered by filtration. The crystals were washed with water and dried by heating under reduced pressure to provide 250 mg of the title compound.
