Procedure

To a solution of 4-[(2-cyclopentyl-4,4,6-trimethyl-5-oxo-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-10-yl)amino]-3-methoxy-benzoic acid (Intermediate 236; 83 mg, 0.19 mmol) in DMF (3 mL) was added a solution of 4-pyrrolidin-1-ylcyclohexan-1-amine (Intermediate 237; 78 mg, 0.46 mmol). DIPEA (100 uL, 0.57 mmol) was added, followed by HATU (107 mg, 0.28 mmol). The resultant mixture was stirred at ambient temperature for 2 hours. The reaction mixture was evaporated to a gum, which was partitioned between DCM (20 mL) and saturated aqueous sodium bicarbonate solution (20 mL). The organic phase was separated by gravity elution through a PTFE filter cup and evaporated to an amber gum which was purified by base modified reverse phase preparative HPLC to yield the title compound as an off white solid (34 mg, 30%).
