Procedure

4-(9-Cyclopentyl-5,7,7-trimethyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxybenzoic acid (Intermediate 6) (20 mg, 0.046 mmol, 1 eq), DIPEA (16 μl, 0.091 mmol, 2 eq) and TBTU (16 mg, 0.05 mmol, 1.1 eq) were added to 0.5 mL DMF and the resulting solution stirred at rt for 5 min before the addition of 3-aminoquinuclidine dihydrochloride (11 mg, 0.055 mmol, 1.1 eq). The RM was then stirred at rt for 16 hours before purifying by preparative RP-HPLC-MS (Preparative—1) to provide (±)-4-(9-cyclopentyl-5,7,7-trimethyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-N-(quinuclidin-3-yl)benzamide (8 mg, 32%).
