실험 절차

EDC (347 mg, 1.81 mmol) and HOBT (254 mg, 1.88 mmol) were added to mixture of p-toluidine (129 mg, 1.20 mmol) and 3-benzoylpropionic acid 27 (218 mg, 1.21 mmol) in 1,4-dioxane (3 mL) at room temperature. It was stirred for 20 minutes and then added triethylamine (0.5 mL, 3.59 mmol). The reaction mixture was stirred for 20 h at room temperature and the solvent was evaporated under vacuum. The residue was purified by flash silica gel column chromatography (hexane:ethyl acetate=3:1 to 2:1) yielded the compound 28 (252 mg, 78%). 1H-NMR (CDCl3, 300 MHz) δ 2.30 (s, 3H), 2.80 (t, J=6.3 Hz, 2H), 3.45 (t, J=6.3 Hz, 2H), 7.10 (d, J=8.4 Hz, 2H), 7.39 (d, J=8.4 Hz, 2H), 7.47 (m, 2H), 7.58 (m, 1H), 7.99 (m, 1H).
