Potassium Carbonate → HCID 22050640, compound

Participants

Reaction Steps

1-Bromomethyl-4-trifluoromethoxybenzene (3.32 g, 13.04 mmol) and potassium carbonate (3.51 g, 25.46 mmol) were added to a mixture of 4-benzyloxy-1H-pyridin-2-one (2.5 g, 12.42 mmol) in acetonitrile (10 ml). The reaction mixture was heated at reflux temperature for 24 hours. After cooling to room temperature, it was filtered through diatomaceous earth, the solid residues were washed with methanol and the combined organic extracts were evaporated in vacuo. The crude residue thus obtained was precipitated with DIPE to yield intermediate D14 (4.5 g, 96%) as a white solid.
