YieldReaction ConditionsOperation in experiment
43.3% With hydrogenchloride; In ethanol; water; for 48.0h;Reflux; [00175] To a solution of 2-(3,4-difluorophenyl)- l-phenylethanone (Intermediate 12)(150 mg, 0.65 mmol), <strong>[178686-24-3]3-ethoxy-4-hydroxy-5-nitrobenzaldehyde</strong> (128.1 mg, 0.65 mmol), and urea (117 mg, 1.95 mmol) in 20 mL of ethanol was added 0.2 ml con. HCl. The mixture was refluxed for 2 days. After the solvent was removed under reduced pressure, the residue was purified by reverse-phase preparatory HPLC (26-53% acetonitrile + 0.1% trifluoroacetic acid in water + 0.1 % trifluoroacetic acid, over 15 min.) to give Compound 30 (132 mg, yield 43.3%). 1H NMR (DMSO- 6 400 MHz): delta 10.30 (s, 1H), 8.82 (s, 1H), 7.58 (s, 1H), 7.43 (s, 1H), 7.30-7.20 (m, 6H), 7.07 (m, 1H), 6.86 (m, 1H), 6.59 (s, 1H), 5.27 (s, 1H), 4.08 (m, 2H), 1.33 (t, J = 6.8 Hz, 3H); MS(ESI): mJz 468.0 [M+l]+
