Reaction Steps

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 (1.0M 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 trans4-{2-[methanesulfonyl-(3-phenyl-allyl)-amino]-ethoxy}-benzoic acid methyl ester (70 mg). 1NMR (400 MHz, CDCl3) δ 7.97 (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).
