Potassium Carbonate → HCID 58042433, compound

Participants

Reaction Steps

Ethyl 2,4,5-trifluorobenzoate (135 mg, 0.661 mmol) and potassium carbonate (156 mg, 1.129 mmol) were dissolved in DMSO (3.0 mL). 5-Chloro-6-isobutoxypyridin-3-ol (Preparation 16, 127.5 mg, 0.632 mmol) was added portion wise and the mixture was stirred at room temperature for 2 hours. The reaction was diluted in EtOAc (10.0 mL) and washed with brine (3×10 mL). The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by silica gel chromatography eluting with 0 to 10% EtOAc in heptane to yield the title compound as a clear oil that solidified upon standing (155 mg, 35%):
