実験手順

To a solution of (2-ethoxy-3-trifluoromethoxybenzyl)methylamine (0.720 g, 2.08 mmol) in CH2Cl2 (25 mL), was added acryloyl chloride (0.25 mL, 3.15 mmol) drop-wise. After stirring for five minutes, triethylamine (0.43 mL, 3.15 mmol) was added. The solution was allowed to stir under N2 for 3 h. The solution was diluted with CH2Cl2 (30 mL) and then washed with H2O (3×50 mL) and brine (2×100 mL), dried (Na2SO4) and concentrated to yield the title compound (0.746 g, 86%) as a yellow oil and as a mixture of amide rotamers: 1H NMR (500 MHz, CDCl3) δ 7.21-7.02 (m, 3H), 6.67-6.50 (m, 1H), 6.41-6.36 (m, 1H), 5.75-5.58 (m, 1H), 4.75-4.65 (m, 2H), 4.14-4.05 (m, 2H), 3.03-2.99 (m, 3H), 1.43-141 (m, 3H).
