Procedure
A mixture of 4-cyanophenol, 125.0 g (1.05 mole), bromochloropropane, 189.0 g (1.2 mole) and potassium carbonate, 145.0 g (1.05 mole) was heated overnight at reflux in 750 ml of acetone. The reaction mixture was filtered and stripped to dryness. The resulting residue was dissolved in chloroform and extracted with 5% sodium hydroxide. Removal of chloroform gave an oil which crystallized to a white solid. A 5 g sample was recrystallized from isopropyl ether. This furnished 1.22 g (24.4%) of white solid, m.p. 40°-44° C. which contained a dimer impurity.
