실험 절차

The mixture of 4-hydroxy-3-nitro-5-propoxybenzaldehyde (Intermediate 65) (126 mg, 0.56 mmol), 1,2-diphenylethanone (131 mg, 0.672 mmol), urea (100 mg, 1.68 mmol) and concentrated hydrochloric acid (0.1 mL) in ethanol (5 mL) was stirred at reflux (110° C.) under N2 overnight. The reaction was concentrated and purified by silica gel column chromatography, followed by preparative HPLC to give Compound 130 (27 mg, yield 10.8%) as a solid. 1H NMR (DMSO-d6 400 MHz): δ 10.27 (s, 1H), 8.72 (d, J=1.6 Hz, 1H), 7.54 (s, 1H), 7.45 (d, J=2.0 Hz, 1H), 7.18-7.27 (m, 6H), 7.00-7.06 (m, 3H), 6.82-6.84 (m, 2H), 5.197 (d, J=2.8 Hz, 1H), 3.90-3.97 (m, 2H), 1.71-1.76 (m, 2H), 0.970 (t, J=7.6 Hz, 3H); MS (ESI): m/z 446.3 [M+1]+.
