Reaction Steps

A mixture of N-hydroxyphthalimide (16.3 g, 100 mmol) and 1,3-dibromopropane (20.19 g, 100 mmol) in dry DMF (150 mL) and triethyl amine (15.33 mL, 110 mmol) is stirred at 20 to 75° C. for 1 to 10 hours. After filtration, the mixture is evaporated to dryness in vacuo. The residue is purified by silica gel flash column chromatography to give the title compound.
