Procedure
92.8 g of 3,4-dimethylbenzyl chloride and 116.7 g of potassium salt of phthalimide were dissolved in 600 ml of DMF and the solution was heated under reflux for 20 hours. After cooling, insoluble materials were removed by filtration and the filtrate was concentrated. The residue was dissolved in chloroform, washed with 0.1 N aqueous sodium hydroxide and then with water, and concentrated. 140 g of 4-phthalimidomethyl-o-xylene was obtained by recrystallization from a chloroform-ether mixed solvent.
