Reaction Steps

A suspension of 1.17 g (8.23 mmol) of 4-fluoro-2-(hydroxymethyl)phenol from Example 34A, 2.59 g (12.63 mmol) of 1-bromo-4-[bromo(difluoro)methyl]benzene from Example 33A and 1.25 g (9.06 mmol) of potassium carbonate in 10 ml of 2-propanol is heated to reflux for 12 hours. The mixture is then concentrated to dryness. The residue is suspended in methylene chloride, absorbed on silica gel, dried in vacuo and purified by chromatography (mobile phase: cyclohexane/ethyl acetate 10:1, then 100% ethyl acetate). 1.02 g (2.95 mmol, 35% yield) of the title compound are obtained.
