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) (66 mg, 0.15 mmol, 1 eq), DIPEA (52 μl, 0.3 mmol, 2 eq) and TBTU (54 mg, 0.17 mmol, 1.1 eq) were added to 1.5 mL DMF and the resulting solution was stirred at rt for 20 min before the addition of 4-morpholinocyclohexanamine (Intermediate 16) (33 mg, 0.18 mmol, 1.2 eq). The RM was then stirred at rt for 2 hours before purifying by preparative RP-HPLC-MS (Preparative—2) 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-((trans)-4-morpholinocyclohexyl)benzamide (off-white solid, 13 mg, 14%).
