反応手順

A mixture of catechol (11 g., 0.1 mole), chloroacetonitrile (5.3 g., 0.07 mole), finely powdered potassium carbonate (11.1 g., 0.08 mole) and acetone (75 ml.) is refluxed with stirring for 2 hours. The mixture then is treated with chloroacetonitrile (3.8 g., 0.05 mole) and potassium carbonate (7.6 g., 0.055 mole) and refluxed for 4 hours. The mixture is filtered, the solids washed with more acetone and the combined filtrate evaporated in vacuo to give an oil. The oil is dissolved in dilute sodium hydroxide solution, extracted with ether to remove 1,2-dicyanomethoxybenzene and the alkali solution acidified and extracted with ether. The extract is evaporated to dryness and the residue distilled in vacuo to give 2-(2-hydroxyphenoxy)acetonitrile.
