Reaction Steps

To a stirred solution of 3,5-dichloro-4-piperidin-1-ylmethylphenol (290 mg, 1.1 mmol) and pyridine (0.36 mL, 4.5 mmol) in DCM (10 mL) at −20° C. was added trifluoromethanesulfonyl chloride (0.38 mL, 2.2 mmol). After the addition was complete the reaction was allowed to warm to ambient temperature and stirred for 10 minutes. The mixture was diluted with DCM (20 mL), washed with water (10 mL). The organic phase was separated, dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to afford a residue that was purified by flash chromatography (silica, 12 g column, ISCO, 0-100% ethyl acetate in cyclohexane) to afford the title compound as a colourless oil (334 mg, 76%). 1H NMR (CDCl3, 300 MHz): 7.26 (s, 2H), 3.66 (s, 2H), 2.53-2.44 (m, 4H), 1.58-1.48 (m, 4H), 1.50-1.34 (m, 2H).
