実験手順

To a mixture of 0.08 g (0.17 mmole) of 4-(7,7-difluoro-5-methyl-6-oxo-9-phenethyl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-benzoic acid (I-275), 0.12 mL (0.64 mmole) of ethyldiisopropyl amine and 0.018 g (0.19 mmole) of tetrahydro-pyran-4-ylamine in 2.0 mL of dimethylformamide was added 0.079 g (0.19 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 mixture was extracted with dichloromethane 3 times. The combined organic layers were washed three times with sodium carbonate, three times with brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. Purification by silica gel chromatography, eluting with dichloromethane-methanol (gradient, 100:0-95:5) gave 0.070 g of 4-(7,7-difluoro-5-methyl-6-oxo-9-phenethyl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-N-(tetrahydro-pyran-4-yl)-benzamide (I-280) as a white solid.
