Reaction Steps

To a solution of 4-[2-fluoro-3-(trifluoromethoxy)phenyl]-1-propylpiperidine (1.92 g, 6.3 mmol) in N,N-dimethylformamide (20 ml) was added a solution of sodium methoxide in methanol (30%, 3 ml) and the mixture was heated to 150° C. for 1 h. Water (50 ml) and ethyl acetate (50 ml) was added and the phases were separated. The aqueous phase was extracted with ethyl acetate (2×50 ml) and the combined organic phases was dried (MgSO4) and evaporated under reduced pressure to give an oil. The residue was purified by flash column chromatography (ethyl acetate/methanol, 1:1) to give the title compound (1.32 g). MS m/z (rel. intensity, 70 eV) 317 (M+, 6), 289 (17), 288 (bp), 204 (6), 175 (8).
