1-(3-fluorophenyl)-2-phenylethanone

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 1-(3-fluorophenyl)-2-phenylethanone (100 mg, 0.47 mmol), 3-ethoxy-4-hydroxy-5-nitrobenzaldehyde (82 mg, 0.39 mmol), urea (70 mg, 1.17 mmol), and concentrated HCl solution (0.03 mL, 0.39 mmol) in EtOH (5 mL) was refluxed overnight. The mixture was evaporated in vacuo and purified by preparative HPLC to give Compound 32 (22.35 mg, yield 13%) as a yellow solid. 1H NMR (DMSO-d6 400 MHz): δ 10.28 (s, 1H), 8.79 (s, 1H), 7.56 (s, 1H), 7.42 (s, 1H), 7.30-7.25 (m, 1H), 7.16 (s, 1H), 7.12-6.99 (m, 6H), 6.86 (d, J=7.6 Hz, 2H), 5.23 (d, J=2.4 Hz, 1H), 4.04 (q, J=7.2 Hz, 2H), 1.33 (t, J=7.2 Hz, 3H); MS (ESI): m/z 450.0 [M+1]+. was refluxed overnight The mixture was evaporated in vacuo purified by preparative HPLC
