Reaction Steps

A mixture of 3-fluoro-4-hydroxy-5-methoxybenzaldehyde (50 mg, 0.294 mmol), 1,2-diphenylethanone (57.7 mg, 0.294 mmol), urea (52.9 mg, 0.882 mmol), and concentrated HCl solution (0.5 mL) in ethanol (2 mL) was refluxed at 80° C. for 52 h. The reaction mixture was evaporated under reduced pressure, and the residue was purified by preparative HPLC to give Compound 68 (32.1 mg, yield 28%). 1HNMR (DMSO-d6 400 MHZ): δ 9.25 (s, 1H), 8.70 (s, 1H), 7.49 (s, 1H), 7.32-7.26 (m, 5H), 7.11-7.05 (m, 3H), 6.88 (d, J=1.6 Hz, 2H), 6.86-6.79 (m, 2H), 5.11 (d, J=2.8 Hz, 1H), 3.79 (s, 3H); MS (ESI): m/z 391.0 [M+H]+.
