실험 절차

Anhydrous pyridine (0.331 g, 4.2 mmol, 1.2 eq) and ethyl 4-aminobenzoate (0.577 g, 3.50 mmol) were added to a solution of (E)-3-(2-naphthyl)propenoyl chloride (prepared from its corresponding acid) (0.757 g, 3.50 mmo) in anhydrous DCM (15 ml) under Ar. After stirring overnight at room temperature, the white precipitate was filtered, washed with DCM (10 ml) and dried under vacuum to give the amide 42 (0.960 g, 2.78 mmol, 80%) as a white solid, mp 173-175° C. 1H NMR (400 MHz, DMSO-d6) δ 1.30 (3H, t, J 7.2 Hz), 4.28 (2H, t, J 7.2 Hz), 6.97 (1H, d, J 15.4 Hz), 7.54-7.57 (2H, m), 7.7 (1H, d, J 15.4 Hz), 7.77 (1H, dd, J 1.6, 9.2 Hz), 7.84 (2H, d, J 8.8 Hz), 7.93-7.97 (5H, m), 8.15 (1H, s), 10.58 (1H, bs). 13C NMR (100 MHz, DMSO-d6) δ 14.88, 61.09, 119.30, 122.91, 124.18, 124.99, 127.47, 127.83, 128.38, 129.09, 129.36, 130.05, 130.98, 132.82, 133.68, 134.26, 141.64, 144.33, 164.69, 166.01. νmax (solid)/(cm−1) 3357, 1702, 1660, 1619, 1607, 1591, 1521, 1403, 1282. MS (API-ES): m/z 346 [M+H]+ (100%), HRMS (API-ES) m/z found 346.1443 [M+H]+.
