The general procedure was used to convert 4-Ethynyl-phenylamine and (Z)-ethyl-3-iodoacrylate to the title product. Purification by flash chromatography (30% ethyl acetate in hexane as the eluent) gave the analytically pure product as a light yellow oil (350 mg, 90% yield). 1H NMR (400 MHz, CDCl3) δ 7.34-7.32 (d, J=8.4, 2H), 6.60-6.58 (d, J=8.4, 2H), 6.36-6.34 (d, J=11.4, 1H), 6.05-6.02 (d, J=11.4, 1H), 4.28-4.23 (q, J=7.1, 2H), 3.96 (s, 2H), 1.35-1.31 (t, J=7.1, 3H). 13C NMR(100 MHz, CDCl3) δ 165.21, 148.01, 133.78, 125.92, 123.66, 114.54, 111.33, 103.46, 85.59, 60.28, 14.32. Anal. Calcd. for C13H13NO2: C, 72.54; H, 6.09; N, 6.51; Found C, 72.63; H, 6.26; N, 6.32.
