Versuchsvorschrift

A mixture of 0.0704 g (0.153 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-ethoxy-benzoic acid (I-214), 4 mL of dimethylformamide, 0.0776 g (0.198 mmole) of 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium-3-oxide hexafluorophosphate and 0.103 mg (0.804 mmole) of diisopropylethylamine was stirred for 20 minutes, then 0.0175 g (0.327 mmole) of ammonium chloride was added. The reaction mixture was stirred for 1.5 hours and then 150 mL of ethyl acetate and 25 mL of water was added. The organic layer was washed with 25 mL of ammonium chloride solution, 25 mL of water, 25 mL of brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. Purification by silica gel chromatography, eluting with dichloromethane-methanol (gradient, 95:5-80:20) gave 0.0554 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)-3-ethoxy-benzamide (I-223).
