実験手順

To a mixed liquid of 95.0 mg of a mixture of 8-cyclopropyl-4-oxo-1-(tetrahydro-2H-pyran-4-yl)-4,5-dihydro[1,2,4]triazolo[4,3-a]quinoxaline-7-carboxylic acid and 8-bromo-4-oxo-1-(tetrahydro-2H-pyran-4-yl)-4,5-dihydro[1,2,4]triazolo[4,3-a]quinoxaline-7-carboxylic acid, 39.0 mg of isoindoline, 190 μL of diisopropylethylamine, and 1.50 mL of N,N-dimethylformamide was added 156 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 a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with chloroform. The organic layer was washed with saturated brine and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by preparative LC-MS (methanol/0.1% aqueous formic acid solution) to obtain 24.8 mg of 8-cyclopropyl-7-(1,3-dihydro-2H-isoindol-2-ylcarbonyl)-1-(tetrahydro-2H-pyran-4-yl)[1,2,4]triazolo[4,3-a]quinoxalin-4(5H)-one as a pale brown solid.
