Procedure

To a mixture of 0.06 g (0.13 mmole) of 4-(9-cyclopentyl-7,7-difluoro-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-benzoic acid (I-151), 0.08 g (0.21 mmole) of 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium-3-oxide hexafluorophosphate and 2 mL of dimethylformamide was added 0.07 mL (0.41 mmole) diisopropylethylamine. After stirring at room temperature for 30 minutes, 0.042 g (0.41 mmole) of 4-amino-tetrahydropyran was then added. The mixture was stirred at room temperature for 18 hours. The mixture was diluted with ethyl acetate and water. The aqueous phase was extracted twice with ethyl acetate. The combined organic layers were washed with water, then brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was triturated with hot methanol to give 0.014 g of 4-(9-cyclopentyl-7,7-difluoro-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-N-(tetrahydro-pyran-4-yl)-benzamide (I-155).
