Procedure

4-(9′-Cyclopentyl-5′-methyl-6′-oxo-5′,6′,8′,9′-tetrahydrospiro[cyclopropane-1,7′-pyrimido[4,5-b][1,4]diazepine]-2′-ylamino)-3-methoxybenzoic acid (Intermediate 5) (50 mg, 0.11 mmol, 1 eq), DIPEA (38 μL, 0.23 mmol, 2 eq) and TBTU (40 mg, 0.12 mmol, 1.1 eq) were added to 5 mL DCM and the resulting solution stirred at rt for 15 min before the addition of 4-aminomorpholine (12 mg, 0.14 mmol, 1.2 eq). The RM was then stirred at rt for 16 hours before concentrating in vacuo and purifying by preparative RP-HPLC-MS (Preparative 1) to provide 4-(9′-cyclopentyl-5′-methyl-6′-oxo-5′,6′,8′,9′-tetrahydrospiro[cyclopropane-1,7′-pyrimido[4,5-b][1,4]diazepine]-2′-ylamino)-3-methoxy-N-morpholinobenzamide (26 mg, 44%).
