実験手順

4-Aminomethyl tetrahydropyran (13.7 g, 0.119 mol) was added to a solution of N-(4-Fluoro-3-nitrophenyl)acetamide (20.2 g, 0.102 mol) and TEA (20.9 mL, 15.2 g, 0.15 mol) in EtOH (350 mL). The reaction mixture was stirred overnight at reflux. The orange-red solid was collected by filtration, washed with water and dried in vacuo. The filtrate was concentrated. The residue was dissolved in EtOAc, washed with H2O, brine and dried over anhydrous Na2SO4. The crude product was purified by silica gel flash chromatography using EtOAc as eluent. Total yield: 28.9 g (97%). 1H NMR (400 MHz, CHLOROFORM-D) δ 1.4 (m, 2 H), 1.7 (m, 2 H), 1.89-2.00 (m, 1 H), 2.18 (s, 3 H), 3.22 (dd, J=6.44, 5.66 Hz, 2 H), 3.42 (dt, J=11.86, 2.05 Hz, 2 H), 4.02 (dd, J=10.94, 3.71 Hz, 2 H), 6.84 (d, J=9.37 Hz, 1 H), 7.20 (br.s, 1 H), 7.81 (dd, J=9.37, 2.54 Hz, 1 H), 8.09 (d, J=2.54 Hz, 1 H), 8.10-8.12 (m, 1 H).
