実験手順

To a mixture of 0.05 g (0.11 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)-2-fluoro-5-methoxy-benzoic acid (I-169), 0.06 g (0.16 mmole) of 1-[bis(dimethylamino)methylene]-1H-benzotriazolium-3-oxide hexafluorophosphate and 2 mL of dimethylformamide was added 0.06 mL (0.32 mmole) of diisopropylethylamine. After stirring at room temperature for 30 minutes 0.04 g (0.32 mmole) of 4-amino-1-ethylpiperidine was added. The mixture was stirred at room temperature for 18 hours, then diluted with ethyl acetate and water. The aqueous phase was extracted twice with ethyl acetate. The combined organic layers were washed with 1M sodium hydroxide solution then brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography eluting with methanol-dichloromethane (gradient, 0:100-20:80) to give 0.038 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)-2-fluoro-5-methoxy-N-(1-methyl-piperidin-4-yl)-benzamide (I-175).
