실험 절차
24.7 g (126 mmol) of 4-bromo-3-methylbenzonitrile are dissolved in 400 ml of anhydrous dioxane and the medium is then cooled to 0° C. 124 ml (372 mmol) of ethylmagnesium bromide are added dropwise and the medium is then warmed to room temperature and stirred for 4 hours. The reaction medium is treated with 250 ml of 3N HCl and then extracted with a water/ether mixture. A white solid is obtained after trituration from heptane (m=14.5 g, Y=52%).
