Procedure

11.09 g (37 mmoles) of 2-(1-adamantyl)-4bromo anisole dissolved in 85 ml of THF are slowly added to 1 g of magnesium and an iodine crystal. At the beginning of the addition, the reaction mixture is heated until the reaction begins, then the remainder of the solution is added in a manner to maintain a regular reflux. This reaction mixture is heated at reflux for 30 minutes after the end of the addition at which point 2.70 g (37 mmoles) of dry DMF are added. The reaction mixture is then stirred for 30 minutes without heating and then-poured into 300 ml of mixture of 2N aqueous HCl and dichloromethane.
