Reaction Steps

7.5 g of methyl 4-bromo-2-ethyl-6-methylphenylacetate were dissolved in 140 ml of dimethylformamide, 5.5 g of copper cyanide were added, and the mixture was heated for 18 hours at 130° C., until the reaction was complete. The mixture was then cooled to room temperature and diluted with water, and the product was extracted repeatedly using tert-butyl methyl ether. The combined organic phases were dried over magnesium sulphate, concentrated and distilled. This gave 3.4 g (52% of theory) of methyl 4-cyano-2-ethyl-6-methylphenylacetate of a boiling point of 123-130° C. and a melting point of 65-72° C.
