Procedure

To a mixture of 0.105 g (0.23 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), 0.0988 g (0.26 mmole) of 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium-3-oxide hexafluorophosphate, 1 mL of dichloromethane, 0.2 mL of triethylamine was added followed by 0.0199 g (0.13 mmole) of 4-(3-amino-propyl)-piperazine-1-carboxylic acid tert-butyl ester. After stirring 1.5 hours, the mixture was concentrated under reduced pressure. The residue was purified by silica gel chromatography, eluting with acetonitrile-water (gradient, 5:95-0:100) to give 0.0609 g of 4-{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}-piperazine-1-carboxylic acid tert-butyl ester (I-94).
