{3-(5-Chloro-2-difluoromethoxyphenyl)-4-[(pyrazolo[1,5-a]pyrimidine-3-carbonyl)amino]pyrazol-1-yl}acetic acid (3.35 g, 7.25 mmol) was dissolved in DMF (30 mL) and HATU (2.85 g, 9.42 mmol) was added. cis-hexahydropyrrolo[3,4-c]pyrrole-2-carboxylic acid tert-butyl ester (2.0 g, 9.42 mmol) and DIPEA (1.63 mL, 9.42 mmol) were added and the mixture was stirred at room temperature for 17 hours. The volatiles were evaporated and the resultant residue azeotroped with toluene. The solid was partitioned between water and DCM and the organic layer was separated, dried (Na2SO4) and evaporated. The residue was dissolved in DCM (10 mL) and TFA (10 mL) was added. The solution was stirred at room temperature for 4 hours and then evaporated. The residue was dissolved in MeOH and loaded onto an SCX-2 cartridge which had been conditioned with MeOH. After flushing with MeOH, the product was eluted with 2M ammonia in MeOH. The solvent was evaporated and the product was crystallised from MeOH/Et2O. The desired product was obtained as an off-white solid (3.7 g, 90%).
