Reaction Steps

A mixture of 4.6 g (30.6 mmol) of 4-hydroxy 3,5-dimethyl benzaldehyde (Example E), 4.4 g (35 mmol) of benzyl chloride and 4.8 g (35 mmol) of anhydrous potassium carbonate in 100 mL of acetonitrile, is stirred at reflux for 18 hours overnight. The reaction flask and the inorganic salts are washed with fresh acetonitrile and the solvent is removed on a rotary evaporator. A diethyl ether solution of the residue is washed with 2×25 mL of 1N potassium hydroxide solution, brine, dried (magnesium sulfate) and evaporated. Distillation through a short path apparatus affords 6.5 g of the title compound; bp 149°-152° C./0.50 mm (190°-195° C).
