To a solution of 4-(2-methanesulfonylamino-ethoxy)-benzoic acid methyl ester (62 mg, 0.23 mmol) in DMF (10 mL) at 0° C. was added sodium bis(trimethylsilyl)amide (1.0 M in THF, 0.24 mL, 0.24 mmol) dropwise. After 20 minutes, cinnamyl bromide (51 mg, 0.26 mmol) was added and the reaction was stirred at room temperature for 2 h. Aqueous 1N HCl was added and the product was extracted into EtOAc. The organic solution was washed with 1N HCl (3×) followed by brine. The organic solution was dried (Na2SO4), filtered, and concentrated. Radial chromatography (20% EtOAc in hexanes) provided trans-4-{2-[methanesulfonyl-(3-phenyl-allyl)-amino]-ethoxy}-benzoic acid methyl ester (70 mg). 1NMR (400 MHz, CDCl3) δ7.97 (d, 2H), 7.35-7.23 (m, 5H), 6.88 (d, 2H), 6.58 (d, 1H), 6.18 (m, 1H), 4.20 (t, 2H), 4.12 (d, 2H), 3.88 (s, 3H), 3.68 (t, 2H), 2.95 (s, 3H).
