Reaction Steps

To a solution of 35 mg (0.140 mmol) 2-hydroxy-6-methoxy-4-trifluoromethyl-benzoic acid methyl ester in 350 ul N,N-dimethylformamide under nitrogen at room temperature, was added 29 mg (0.210 mmol) potassium carbonate, followed dropwise by 18.1 ul (0.168 mmol) methyl chlorodifluoroacetate. The reaction mixture was heated in a 65° C. oil bath for 22 hours. Water and ethyl acetate were added. Both phases were separated and the organic layer was washed 3 times with water. The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The crude brown oil (49 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 16 mg (y: 38.1%) of the title compound as a light yellow oil.
