실험 절차

To a mixture of 125 mg of 4-oxo-1-propyl-4,5-dihydro[1,2,4]triazolo[4,3-a]quinoxaline-7-carboxylic acid, 73 mg of 1,2,3,4-tetrahydroisoquinoline, 0.26 mL of diisopropylethylamine, and 3 mL of N,N-dimethylformamide was added 262 mg of O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate, followed by stirring at room temperature overnight. To the reaction liquid was added water, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was evaporated. The obtained residue was purified by silica gel column chromatography (chloroform/methanol=99/1 to 95/5). The obtained solid was washed with 2 mL of hot methanol to obtain 159 mg of 7-(3,4-dihydroisoquinolin-2(1H)-ylcarbonyl)-1-propyl[1,2,4]triazolo[4,3-a]quinoxalin-4(5H)-one as a white solid.
