Procedure

220 ml. of a solution of (4-chlorobutyl)benzene (1083 g., 6.42 mole) in 1280 ml. of ether is added to a flask containing magnesium (241.6 g., 0.9 mole) in 834 ml. of ether. The mixture is refluxed and a few crystals of iodine are added. The reaction initiates after about 30 minutes. When the initial reaction subsides, the remaining chloride solution is added at a rate sufficient to maintain reflux (addition time about 1.5 hours). Reflux is maintained an additional 2.5 hours and the mixture is cooled and allowed to stir overnight under argon at room temperature to give the Grignard solution, (4-phenylbutyl) magnesium chloride.
