Reaction Steps

tert-Butyl 2-(3-naphthylcarbonyl-2,4-dioxo-5,5-diphenylimidazolidinyl)acetate (300 mg) was dissolved in a 20% trifluoroacetic acid/dichloromethane solution (2 mL), and the solution was stirred at room temperature overnight. After a 1N aqueous hydrogen chloride solution was added, the solution was extracted three times using chloroform (50 mL). The resulting organic layer was washed with a saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was distilled off. Further, recrystallization from IPE afforded 231 mg of white crystals.
