실험 절차

A mixture of 2-phenyl-1-(pyridin-4-yl)ethanone (Intermediate 35) (60 mg, 0.30 mmol), 3-ethoxy-4-hydroxy-5-nitrobenzaldehyde (58 mg, 0.28 mmol), urea (50 mg, 0.83 mmol), and concentrated HCl solution (0.02 mL, 0.28 mmol) in EtOH (5 mL) was refluxed overnight. The mixture was evaporated in vacuo and purified by preparative HPLC to give Compound 71 (55.17 mg, yield 46%). 1H NMR (DMSO-d6 400 MHz): δ 10.29 (br, 1H), 8.92 (s, 1H), 8.53 (d, J=5.6 Hz, 2H), 7.61 (s, 1H), 7.41 (d, J=1.6 Hz, 1H), 7.35 (d, J=1.6 Hz, 2H), 7.12-7.09 (m, 4H), 6.89 (d, J=7.6 Hz, 2H), 5.31 (d, J=2.8 Hz, 1H), 4.03 (q, J=7.2 Hz, 2H), 1.32 (t, J=7.2 Hz, 3H); MS (ESI): m/z 433.0 [M+1]+.
