실험 절차

To a solution of 2-amino-N-(4-sec-butyl-phenyl)-5-methanesulfonyl-benzamide (0.21 g, 0.58 mmol) and 4-(2-hydroxy-ethoxy)-3,5-dimethyl-benzaldehyde (0.13 g, 0.64 mmol) in anhydrous ethanol (20 mL) was added anhydrous copper (II) chloride (0.440 g, 3.27 mmol) and the reaction mixture was refluxed for 48 hours. The solvent was evaporated in vacuo and the product was extracted with dichloromethane. The solvent was evaporated in vacuo and the residue was triturated with ether and methanol/ethyl acetate and filtered off, to obtain the title compound as a white solid. Yield: 0.13 g (43%). MP 258.8-260.2° C. 1H-NMR (400 MHz, CDCl3): δ 8.94 (s, 1H), 8.28 (d, 1H), 7.94 (d, 1H), 7.19 (m, 2H), 7.03 (m, 2H), 7.01 (s, 2H), 3.91 (m, 2H), 3.79 (d, 2H), 3.17 (s, 3H), 2.58 (m, 1H), 2.18 (s, 3H), 2.03 (m, 1H), 1.60 (m, 2H), 1.21 (d, 3H), 0.78 (t, 3H). MS (ES+) m/z: 521.66 (M+1).
