Reaction Steps

To a stirred solution of (R)-(+)-1-(4-bromophenyl)ethylamine (1 g, 5 mmol), in anhydrous CH2Cl2 (10 mL) under argon were added ethane sulfonyl chloride (0.57 mL, 5.99 mmol) and Pyridine (0.60 mL, 7.5 mmol). The resulting solution was stirred at 25° C. for 3 hrs. The reaction mixture was quenched with 1N HCl and extracted with EtOAc (3×10 mL). The organic phase was washed with brine (50 mL), dried over Na2SO4 and evaporated. The residue was purified by flash column chromatography (80% EtOAc in hexanes) to give the product (0.40 g, 58%) as a white solid. 1H NMR (CDCl3) δ: 1.23 (t, J=7.5 Hz, 3H), 1.52 (d, J=6.8 Hz, 3H), 2.77 (q, J=14, 7.5 Hz, 2H), 4.61-4.72 (m, 2H), 7.24 (d, J=8.3 Hz, 2H), 7.51 (d, J=8.3 Hz, 2H). ESIMS (MH+): 293.
