Reaction Steps
To a solution of 3-(1-ethylpiperidin-4-yl)-2-fluorophenol (0.44 g, 1.97 mmol)) in methylene chloride (20 ml) was added triethylamine (4 ml) and methanesulfonyl chloride (0.56 ml, 3.67 mmol). The mixture was stirred for 20 h and water (50 ml) and methylene chloride (50 ml) was added and the phases were separated. The aqueous phase was extracted with methylene chloride (2×50 ml) and the combined organic phases was dried (MgSO4) and evaporated under reduced pressure to give an oil. Purification by flash column chromatography (ethyl acetate/methanol, 1:1) gave the title compound: 0.39 g (66%). The amine was converted to the oxalic acid salt and recrystallized from ethanol/diethyl ether: M.p. 161.5-163.2. MS m/z (relative intensity, 70 eV) 301 (M+, 15), 287 (15), 286 (bp), 222 (23), 207 (38).
