Procedure

4-[(2-cyclopentyl-6-methyl-5-oxo-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-10-yl)amino]-3-methoxy-benzoic acid (Example 111; 231 mg, 0.56 mmol), DIPEA (0.3 mL, 1.68 mmol) and HATU (283 mg, 0.75 mmol) were stirred together in DMA (4 mL) at ambient temperature for 10 minutes. 4-amino-1-propylpiperidine (Fluorochem; 100 mg, 0.70 mmol) was added and the mixture stirred at room temperature for 4 hours. The reaction mixture was loaded onto an SCX-2 (10 g) column pre-wet with MeOH. The column was washed with MeOH (×2) and the product eluted with 2M NH3/MeOH. Product containing fractions were combined and evaporated and the residue purified by base modified reverse phase preparative HPLC. Product containing fractions were combined and evaporated to yield the title compound as a gum (194 mg, 65%).
