Procedure

To a solution of (S)—N-((3-fluoropyridin-2-yl)(4-(trifluoromethyl)phenyl)-methyl)-5-hydroxypicolinamide (Example 173) (0.145 g, 0.371 mmol) in DCM (2 mL) and DMF (0.2 mL) were added bromoacetic acid t-butyl ester (0.072 mL, 0.445 mmol) and cesium carbonate (0.241 g, 0.741 mmol). The resulting mixture was then stirred at rt for 2 h. Then, the mixture was filtered and the solid was washed with DCM (1×1 mL) and MeOH (1×1 mL). The combined filtrates were concentrated and dried to give the desired product, which was used without further purification in the next step.
