Reaction Steps
Under a nitrogen atmosphere in a flame-dried flask, with magnetic stirring, the potassium salt of imidazolidine-2,4-dione (1.382 g, 10 mmol) and 4-chlorobenzyl bromide (2.055 g, 10 mmol) were combined with 15 mL of anhydrous N,N-dimethylformamide (DMF) and heated to 170-175° C. for 5 hours. The reaction was then cooled to room temperature and poured over 50 mL of water to produce a waxy white precipitate. Recrystallization from ethyl acetate : hexanes produced the title product as a white crystalline solid, 0.775 g (34.5%).
