Procedure

2-Fluoro-6-[1,2,3]triazol-2-yl-benzoic acid (0.97 g, 4.71 mmol), hexahydro-pyrrolo[3,4-c]pyrrole-2-carboxylic acid tert-butyl ester (Intermediate 15, 1.0 g, 4.71 mmol), HATU (2.68 g, 7.06 mmol), in DMF (18.8 mL) was added DIEA (2.43 mL, 14.13 mmol). The mixture was stirred at rt for 1 hr. The mixture was diluted with EtOAc and washed with water. The aqueous layer was extracted with EtOAc, the organic layers were combined, dried (Na2SO4), filtered and concentrated to provide the crude product. Purification (FCC) (5-50% of a solution 10% MeOH, 0.1% NH4OH in DCM/EtOAc over 25 minutes, and 50-100% from 25-35 minutes) provided 5-(2-fluoro-6-[1,2,3]triazol-2-yl-benzoyl)-hexahydro-pyrrolo[3,4-c]pyrrole-2-carboxylic acid tert-butyl ester (0.376 g, 19.5%).
