Reaction Steps

To a mixture of 5-chloro-6-[(1S)-2,2,2-trifluoro-1-methylethoxy]pyridin-3-ol (Preparation 231, 60 mg, 0.25 mmol) and 4-methylphenyl 5-chloro-2,4-difluorobenzoate (Preparation 26, 70 mg, 0.25 mmol) in DMSO (1 mL) was added K2CO3 (69 mg, 0.50 mmol) at room temperature under N2 and the resulting mixture was stirred for 4 hours. The reaction mixture was warmed up to 50° C. and stirred for 1 hour before cooling to room temperature and stirring for 18 hours. The reaction was quenched with water and partitioned between water and DCM (3×5 mL). The mixture was filtered through a phase separation cartridge, the organic phase was washed with brine (3 mL) and filtered through another phase separation cartridge. The filtrate was dried by N2 blowing to give a crude product that was purified by silica gel column chromatography eluting with 0-20% EtOAc in heptane to give the title compound (108 mg, 86%) as colourless gum.
