Procedure

0.20 g (0.42 mmol) 3-{1-[6-(3,4-diamino-5-methyl-phenoxy)-pyrimidin-4-yl]-piperidin-4-yl}-7-methoxy-1,3,4,5-tetrahydro-benzo[d][1,3]diazepin-2-one, 40 mg (0.46 mmol) cyanoacetic acid, 0.15 g (0.47 mmol) TBTU and 0.14 mL (1.00 mmol) TEA in 2.00 mL DMF were stirred for 4 h at RT. Then 2.00 mL glacial acetic acid was added and the mixture was stirred overnight at RT. The reaction mixture was also stirred for 1 h at 100° C., then cooled and purified by preparative HPLC-MS. The product-containing fractions were combined and the acetonitrile was evaporated down. The residue was made alkaline with 4N aqueous sodium hydroxide solution, the precipitate formed was suction filtered, washed with water and dried under HV.
