To a stirring solution of 6-bromo-3-(2,5-dimethyl-1H-pyrrol-1-yl)-5-(trifluoromethyl) picolinic acid (300 mg, 0.826 mmol) in THF (1 ml), pyrrolidine (0.136 ml, 1.652 mmol) was added. The orange solution was stirred at RT overnight. The reaction mixture was partitioned between 0.5M HCl (30 ml) and EtOAc (30 ml) and shaken. The organic portion was separated and washed with brine (30 ml), dried over MgSO4, filtered and concentrated in vacuo to give a red oil. The crude product was purified on silica eluting with 0-40% EtOAc in iso-hexane to afford the title product;
