To a solution of 6-[4-methyl-3-(trifluoromethoxy)phenoxy]pyridin-3-amine (Intermediate 31, 475 mg, 1.67 mmol) and TEA (0.28 mL) in 5 mL of dry DCM under nitrogen at 0° C., acetyl chloride (0.13 mL) dissolved in 2 mL of dry DCM was added drop wise. The ice bath was then removed and the resulting solution was allowed to stir at room temperature for 30 minutes until complete conversion. Water was added and phases were separated. The organic phase was then washed with an aqueous 15% solution of NaHCO3, dried over Na2SO4, filtered and concentrated to give the title compound (502 mg) as yellow oil.
