Procedure

To a mixture of 1,2-diphenylethanone (200 mg, 1.03 mmol), 5-formyl-2-hydroxybenzoic acid (203 mg, 1.22 mmol), and urea (184 mg, 3.06 mmol) in anhydrous EtOH was added concentrated HCl solution (105 mg, 1.03 mmol). The reaction was refluxed for three days. The reaction mixture was concentrated, and purified by column chromatography and preparative HPLC to give Compound 86 as an off-white solid (40 mg, yield 10.2%). 1H NMR (DMSO-d6 400 MHz): δ 11.20 (s, 1H), 8.63 (s, 1H), 7.78 (d, J=2.4 Hz, 1H), 7.42-7.50 (m, 2H), 7.13-7.28 (m, 5H), 6.90-7.00 (m, 4H), 6.75 (d, J=6.4 Hz, 2H), 5.10 (d, J=2.4 Hz, 1H); MS (ESI): m/z 387.1 [M+1]+.
