Reaction Steps
550 g of ethyl bromide are added drop-wise to 470 g of 4-isobutylphenyl acetonitrile, 1550 g of a 50% solution of sodium hydroxide and 11.4 g of triethylbenzyl ammonium chloride. The addition is complete within 2 hours. During this addition, the temperature must be controlled such that it does not exceed 40° C. The mixture is agitated for 10 hours at 40° C. After cooling of the mixture, the alkaline phase is discarded and the organic layer is washed with water until neutral. Fractionation yields 536 g of crude 2-(4-isobutylphenyl)butyronitrile.
