Versuchsvorschrift

The title compound was prepared as described in General Method 2 using 17.40 g (138 mmol) of cyclohexyl methyl ketone, 29.26 g (138 mmol) of 4-benzyloxybenzaldehyde, 3.17 g of barium hydroxide (anhydrous), and 300 mL of 95% EtOH. The reaction was heated at reflux for eight hours. The crude product was recrystallized from EtOAc. The 25.85 g of product, contaminated with some 4-benzyloxybenzaldehyde, was taken on without further purification.
