実験手順
To a mixture of 0.050 g (0.075 mmole) of rac-(3S,4R)-4-[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-benzoylamino]-3-methoxy-piperidine-1-carboxylic acid tert-butyl ester (I-56) and 1 mL of dichloromethane was added 1 mL of trifluoroacetic acid-dichloromethane (25:75). The mixture was stirred for 1.5 hours, and then concentrated under reduced pressure. The residue was dissolved in methanol, and the mixture neutralized by the addition of 1M sodium hydroxide at 0 degrees. The mixture was purified by reverse phase silica gel chromatography, eluting with acetonitrile-water (gradient, 1:99-90:10) to give 0.0156 g of rac-(3S,4R)-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-(3-methoxy-piperidin-4-yl)-benzamide (I-57).
