Procedure

5-chloro-4-[(2-cyclopentyl-6-methyl-5-oxo-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-10-yl)amino]-2-fluoro-benzoic acid (Intermediate 219; 100 mg, 0.23 mmol), 4-amino-1-methylpiperidine (Fluorochem; 40 mg, 0.35 mmol) and HATU (132 mg, 0.35 mmol) were stirred in DMF (3 mL). N,N-diisopropylethylamine (121 μl, 0.69 mmol) was added and the mixture heated at 50° C. for 2 hours. The mixture was cooled and absorbed on to an SCX column, which was subsequently washed with methanol and eluted with ammonia in methanol. Product containing fractions were concentrated and the residue purified by base modified reverse phase preparative chromatography to yield the title compound as a white solid (58 mg, 48%)
