Procedure

To a solution of 380 mg (1.165 mmol) 2-benzyloxy-6-methoxy-4-trifluoromethyl-benzoic acid in 3.8 ml N,N-dimethylformamide under nitrogen at room temperature, was added 177.1 mg (1.281 mmol) potassium carbonate and 87.2 ul (1.398 mmol) methyliodide. The mixture was stirred under nitrogen for 3 days. The mixture was poured into water. The aqueous layer was extracted once with ethyl acetate. The organic layer was washed once with water, dried over sodium sulfate, filtered and concentrated in vacuo. The crude light yellow oil (410 mg) was purified with flash column chromatography on silica (10 g) eluting with a gradient formed from n-heptane and ethyl acetate (0%=>10% in 15 minutes) to provide 352 mg (y: 88.8%) of the title compound as a colorless oil, which crystallized on standing. MS (m/e): 341.2 (MH+).
