実験手順
To the suspension 0.12 g (0.16 mmole) of {3-[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]-propyl}-carbamic acid 9H-fluoren-9-ylmethyl ester (I-73) in 2 mL of dichloromethane was added 0.4 mL of piperidine. The mixture was stirred at room temperature for 1 hour, then volatiles were removed under reduced pressure. Purification by silica gel chromatography, eluting with dichloromethane-methanol (gradient, 100:0-0:100) gave 0.027 g of N-(3-amino-propyl)-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-benzamide (I-74) as a white solid.
