A solution of N-(4-(3-benzyloxyphenyl)pyridin-3-ylmethylamine (1.0 equiv.) in 2:1 DCE/Pyridine (0.15 M) was cooled to 0° C. and treated with 2,2,2-trifluoroethanesulfonyl chloride (1.8 equiv.). The mixture was allowed to warm to ambient temperature and stir overnight. The reaction was treated with anhydrous potassium carbonate, stirred for 40 min, and filtered. The filtrate was purified via preparative HPLC eluting with 70:30 to 60:40 DCM/ethyl acetate, evaporated, and then triturated with diethyl ether to give the title compound.
