실험 절차

To a mixture of 0.10 g (0.22 mmole) of 4-(9-cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-benzoic acid (I-22), 0.12 mL (0.66 mmole) of ethyldiisopropyl amine and 0.039 g (0.25 mmole) of 2,2,6,6-tetramethyl-piperidin-4-ylamine in 2.0 mL of dimethylformamide was added 0.11 g (0.25 mmole) of 1-(di-1-pyrrolidinylmethylene)-1H-benzotriazolium 3-oxide hexafluorophosphate. The mixture was stirred at room temperature for 1 hour, then diluted with 10 mL of ice water. The resulting solid was collected by filtration, washed with saturated sodium carbonate and water, and dried under vacuum. Purification by silica gel chromatography, eluting with dichloromethane-methanol (gradient, 100:0-60:40) gave 0.065 g of 4-(9-cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-N-(2,2,6,6-tetramethyl-piperidin-4-yl)-benzamide (I-65) as a white solid.
