Procedure

To a 250 round bottom flask fitted with a condenser, nitrogen inlet and an overhead stirrer (IKA), was added 6 grams of chloromethyl paramagnetic beads prepared as in Example 2, 100 ml of dimethylformamide and 1.2 grams (6.4 mmole) potassium phthalimide and mixture stirred at 50° C. for 20 hours. At the end of 20 hours, the product was washed with dimethylformamide, methanol, water and ethanol and then dried under vacuum to provide phthalimide incorporated beads.
