To a stirred solution of 3-(5-Bromo-2-fluoro-phenyl)-propan-1-ol (0.53 g, 2.3 mmol) in dry methylene chloride (10 mL) at 0° C. and under a nitrogen atmosphere was added pyridine (0.46 mL, 5.6 mmol) and tosyl chloride (0.47, 2.5 mmol). The cooling bath was removed and the mixture was warmed to room temperature for 12 h, and then quenched with 2 N HCl (6 mL). The mixture was partitioned between methylene chloride and H2O, and the aqueous layer was extracted with methylene chloride (2×10 mL). The organic layer was washed with brine and dried over MgSO4, filtered and concentrated in vacuo. The crude material was purified by silica gel chromatography (10-20% Ethyl acetate/Petroleum Ether) to afford the titled compound (0.6 g, 69%) as a clear oil, identified by NMR and mass spectral analyses; MS (ES+): 403 (M+NH4+).
