2-Chloro-5-(4-methoxy-benzoyl)-benzenesulfonyl chloride (0.2 g, 5.79 mmol) is dissolved in methylene chloride (10 mL). Phenethylamine (0.077 g, 6.36 mmol) is added, followed by the addition of triethylamine (0.146 g, 14.5 mmol). The reaction mixture is stirred for 2 h at room temperature. Water is added, and the mixture extracted with methylene chloride. The solvent is removed and the mixture is purified by flash column chromatography, using 50% of ethyl acetate-hexane as an eluent. The product is obtained as a colorless oil (0.13 g, 52% yield). 1H NMR (CDCl3): δ 8.4 (m, 1H), 7.90 (m, 1H), 7.50 (d, J=8 Hz, 2H), 7.28 (m, 3H), 7.00 (d, J=8 Hz, 2H), 7.17 (m, 2H), 4.97 (m, 1H), 3.91 (s, 3H), 3.20 (m, 2H), 2.80 (m, 2H). Analytics calculated for C22H20ClNO4S: C, 61.46; H, 4.69; N, 3.26. Found: C, 61.20; H, 4.95; N, 3.10. MS (m/z): 430.0 (M+1).
