Versuchsvorschrift

To a mixture of 2-(2-chlorophenyl)-1-phenylethanone (Intermediate 10) (85 mg, 0.37 mmol), 3-ethoxy-4-hydroxy-5-nitrobenzaldehyde (94 mg, 0.45 mmol), and urea (67 mg, 1.1 mmol) in anhydrous EtOH (20 mL) was added concentrated HCl solution (0.1 mL), and the reaction mixture was refluxed for three days. TLC (EtOAc:MeOH=10:1) showed that about 50% of starting materials were consumed, and the reaction mixture was concentrated. The residue was purified by column chromatography (EtOAc:MeOH=40:1) and preparative HPLC to afford Compound 28 as a yellow solid (12 mg, yield: 7.0%). 1H NMR (CD3OD 400 MHz): δ 7.47 (s, 1H), 7.34-7.40 (m, 1H), 7.20 (s, 5H), 7.10-7.13 (m, 1H), 7.05 (s, 1H), 6.80-6.87 (m, 1H), 6.40-6.45 (m, 1H), 5.45 (s, 1H), 3.95-4.10 (m, 2H), 1.37-1.42 (m, 3H); MS (ESI): m/z 466.2 [M+1]+.
