Versuchsvorschrift
A mixture of 2,4,6-triisopropylbenzyl bromide (5.00 g, 16.8 mmol), potassium phthalimide (3.71 g, 19.9 mmol), and dimethylformamide were heated for 3 hours at 70° C. The reaction mixture was allowed to stand overnight at room temperature and was then heated at 90° C. for 1 hour. The solvent was removed on the rotary evaporator, ethyl acetate (250 mL) was added, the organic layer was washed with brine, dried over magnesium sulfate, filtered, and concentrated to a white solid. Hexanes (50 mL) and ethyl acetate (5 mL) was added and the solid collected by filtration, 4.18 g (68%). An analytical sample was obtained by silica gel filtration using 9:1, hexanes/ethyl acetate as eluant.
