Procedure

The crude solid (3 g) from step 3 above mixed with triphenyl phosphite (4 mL, 14.81 mmol) in pyridine (15 mL) was stirred at rt for 4 h. The mixture was added with phenethylamine (1.55 mL, 12.18 mmol), irradiated with microwave 250 W to refluxing for 15 min. The mixture was diluted with ethyl acetate (50 mL), washed with water (2×50 mL). The ethyl acetated solution was mixed with water (50 mL) and kept at rt to give solid form. The solution was filtered to give yellow solid title compound (1.1 g, 27.2%). mp=150-152° C. (recrystallized from ethyl acetate); 1H NMR (400 MHz, DMSO-d6) δ 1.19 (t, J=7.2 Hz, 3H, CH3), 2.76 (q, J=7.2 Hz, 2H, CH2), 2.93 (br t, J=7.6 Hz, 2H, CH2), 4.19 (br t, J=7.6 Hz, 2H, CH2), 7.20-7.31 (m, 5H, ArH), 7.80 (d, J=6.4 Hz, 1H, ArH), 7.91 (d, J=8.8 Hz, 1H, ArH), 13C NMR (100 MHz, DMSO-d6) δ 10.6, 26.9, 33.5, 44.8, 112.2, 112.4, 119.8, 119.9, 126.6, 126.8, 127.0, 128.5, 128.7, 128.8, 138.0, 144.1, 153.6, 156.1, 158.9, 160.0; Anal. (C18H16ClFN2O) C, H, N. Calcd: 65.36, 4.88, 8.47. Found: 65.09, 4.77, 8.50.
