Participants

Reaction Steps

The title compound was prepared as described in General Method 1 using 42.4 g (0.2 mol) 4-benzyloxybenzaldehyde, 700 mL absolute ethanol (EtOH), 5.8 g (0.1 mol) acetone and 10 mL 10% NaOH. The reaction was refluxed for 2 hours. After cooling the reaction was filtered, and the resultant solid dried. It was used without further purification in the next reaction. 1H NMR (CDCl3) δ 5.11 (s, 4 H), 6.91-7.01 (m, 6 H), 7.34-7.45 (m, 10 H), 7.57 (m, 4 H), 7.69 (d, 2 H).
