Reaction Steps

To a solution of 3-fluoro-4-trifluoromethylpyridine (1 g, 6.1 mmol) and [2-(4-hydroxyphenyl)-ethyl]-carbamic acid tert-butyl ester (1.44 g, 6.1 mmol) in DMSO (10 mL) was added K2CO3 (5 g, 36.2 mmol), and the mixture was heated at 100° C. for 30 min. After cooling, the solids were removed by suction filtration and washed with Et2O. The pooled filtrates were diluted with Et2O (75 mL) and washed with 0.01 N HCl. The organic layer was concentrated in vacuo. The residue was dissolved in Et2O/hexane and washed with 10% NaOH. The organic layer was filtered and vacuum dried to provide 1.4 g (60% yield) of {2-[4-(4-trifluoromethyl-pyridin-3-yloxy)-phenyl]-ethyl}-carbamic acid tert-butyl ester as a clear, colorless oil.
