A suspension of the 3-(benzhydrylidene-amino)-phenol (10.47 g, 38.3 mmol), 3-chloro-cyclohex-2-enone (5.00 g, 38.3 mmol) and potassium carbonate (5.82, 42.1 mmol) in 150 mL of acetone was heated at reflux overtight. The cooled reaction mixture was filtered and concentrated under reduced pressure. The residue was chromatographed on silica gel eluting hexanes/EtOAc (2:1). In this manner, 3-[3-(benzhydrylidene-amino)-phenoxy]-cyclohex-2-enone was obtained as a yellow solid, (8.82 g, 63%): 1H NMR (CDCl3) δ 7.78 (d, 2H, J=7.0 Hz), 7.50 (d, 1H, J=7.1 Hz), 7.45 (d, 2H, J=7.7 Hz), 7.34-7.10 (m, 6H), 6.69 d, 1H, J=8.0 Hz), 6.61 (d, 1H, J=8.0 Hz), 6.38 (s, 1H), 4.89 (s, 1H), 2.55 (t, 2H, J=6.2 Hz), 2.34 (t, 2H, J=6.2 Hz), 2.06 (m, 2H). Anal. Calc. for C25H21NO2 O.0.2H2O: C, 80.92; H, 5.81; N, 3.78. Found: C, 81.12; H, 5.81; N, 3.72.
