Procedure

2-chloro-4-[(2-cyclopentyl-6-methyl-5-oxo-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-10-yl)amino]-5-methoxy-benzoic acid (Intermediate 231; 100 mg, 0.224 mmol), (3R)-1-methylpyrrolidin-3-amine di Hydrochloride (Intermediate 184; 40 mg, 0.235 mmol), HATU (94 mg, 0.246 mmol) and DIPEA (195 μL, 1.12 mmol) were combined in DMF (3 mL) and stirred at room temperature overnight. The reaction mixture was added to an SCX-2 column (5 g) pre-wet with MeOH (2 column volumes), flushed with MeOH (2 column volumes) and eluted with 2M ammonia in MeOH. Product containing fractions were combined and evaporated and the resultant material purified by base modified reverse phase preparative HPLC to yield the title compound as a white solid (76 mg, 64%).
