Reaction Steps

The title compound was prepared by stirring a mixture of 2,5-bis(2,2,2-trifluoroethoxy)acetophenone (200 mg, 0.633 mmol), 4-chlorobenzaldehyde (89 mg, 0.633 mmol), methanol (5 ml) and saturated NaOH (200 ul) at room temperature for 4 h. The mixture was diluted with ethyl acetate (100 ml), wash with water (50 ml) and saturated aqueous NaCl (50 ml), dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography using hexane:ethyl acetate (5:1, 4:1) to give a yellow solid (143 mg, 51%). 1H NMR (CDCl3): 7.65 (d, J=15.9 Hz, 1H), 7.54 (d, J=8.4 Hz, 2H), 7.44 (d, J=15.9 Hz, 1H), 7.38 (d, J=8.4 Hz, 2H), 7.31 (d, J=3.3 Hz, 1H), 7.14 (dd, J=3.3, 9.3 Hz, 1H), 6.95 (d, J=9.0 Hz, 1H), 4.45-4.32 (m, 4H).
