Reaction Steps
A mixture of 5-(4-bromo-phenyl)-5-methyl-imidazolidine-2,4-dione (4.0 g, 14.9 mmol) and 3 N NaOH (50 mL) was heated in a sealed tube at 145° C. for two days, then diluted with water (100 mL). The solution was adjusted to pH=4 with 6 N HCl carefully and subsequently stirred at room temperature for 2 hours. The precipitate was filtered off, washed with water. The collected white solid was dried under vacuum to give the product (2.5 g, 65%). m/z 243.7, 245.7 (M+H)+.
