実験手順

p-Cyanophenol (19.4 g) and 2,6-bis(chloromethyl)-4-fluorophenol (17.0 g) were dissolved in nitrobenzene (250 ml) at 20°. The solution was cooled to 10° and crushed aluminium chloride (anhydrous 65 g) was added in 5 g portions over two hours. During the addition the temperature was maintained at 10°-12°. Stirring was continued at 20° for 14 hrs. The viscous black mixture was poured onto a vigorously stirred mixture of ice (2 l) and dichloro methane (2 l). The organic solvent layer was dried, dichloro methane and nitrobenzene removed by vacuum distillation and the residual tar passed through a silica column. The product, 2,6-bis(5-cyano-2-hydroxybenzyl)-4-fluorophenol (mp 222°) was obtained in 3% yield.
