Reaction Steps

1-Methylimidazolidine-2,4-dione (0.876 mmol, 100 mg), 1-bromo-4-(bromomethyl)benzene (0.964 mmol, 241 mg) and potassium carbonate (1.75 mmol, 242 mg) in acetonitrile (3 ml) were heated in the microwave at 120° C. for 1 h. The mixture was partitioned between water and DCM and the organic phase separated using a hydrophobic frit and concentrated to afford 3-(4-bromobenzyl)-1-methylimidazolidine-2,4-dione (3D3); 1H NMR (400 MHz, CDCl3) δ 7.44 (d, 2H) 7.29 (d, 2H) 4.59 (s, 2H) 3.85 (s, 2H) 2.98 (s, 3H).
