Procedure

4-(9-Cyclopentyl-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-N-(piperidin-4-yl)benzamide (Intermediate 12) (35 mg, 0.07 mmol, 1 eq) and sodium triacetoxyborohydride (18 mg, 0.084 mmol, 1.2 eq) in DCM (0.5 mL) were reacted with tetrahydropyran-4-one (6.5 μL, 0.07 mmol, 1 eq) at rt for 2 days. Further and sodium triacetoxyborohydride (18 mg, 1.2 eq), tetrahydropyran-4-one (6.5 μL, 1 eq) were added and acetic acid (4 μL, 1 eq). After two days the RM was diluted with DCM, washed with water and the organic layer concentrated in vacuo. The resulting residue was purified by preparative RP-HPLC-MS (Preparative—1) to provide 4-(9-cyclopentyl-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-N-[1-(tetrahydro-pyran-4-yl)-piperidin-4-yl]-benzamide (10 mg, 25%).
