Reaction Steps

A mixture of 1-(3-chloro-5-fluorophenyl)-2-phenylethanone (Intermediate 60) (150 mg, 0.60 mmol), 3-ethoxy-4-hydroxy-5-nitrobenzaldehyde (116 mg, 0.55 mmol), urea (99 mg, 1.65 mmol), concentrated HCl (0.05 mL, 0.55 mmol) in EtOH (5 mL) was refluxed overnight. Followed standard aqueous/EtOAc workup and purified by preparative HPLC to give Compound 121 (155 mg, yield 58%). 1H NMR (DMSO-d6 400 MHz): δ 10.27 (brs, 1H), 8.85 (s, 1H), 7.58 (s, 1H), 7.40 (d, J=1.6 Hz, 1H), 7.34 (d, J=8.8 Hz, 1H), 7.25 (s, 1H), 7.12 (d, J=6.4 Hz, 2H), 7.08 (d, J=7.6 Hz, 2H), 7.01 (d, J=7.2 Hz, 1H), 6.88 (d, J=7.2 Hz, 2H), 5.27 (d, J=2.4 Hz, 1H), 4.09-3.99 (m, 2H), 1.32 (t, J=7.2 Hz, 3H); MS (ESI): m/z 484.1 [M+1]+.
