The mixture was aged for 8 hours. 9 g of HMPA (available from Aldrich Chemical Company) was added and the mixture was stirred. 144 g of CH3I was added dropwise to the reaction mixture, further aged for two hours and then sampled hourly until maximum conversion was reached. The mixture was cooled and 800 ml of 5% HCl solution was added, allowed to settle, and the organic layer was separated. The aqueous layer was extracted with 3×100 ml of toluene and then dried over MgSO4 to provide 3-nonene, 7-methoxy-3,7-dimethyl-.
