Reaction Steps

α-Aminoisobutyric acid methyl ester (3.2 g, 20.92 mmol) and N,N-diisopropylethylamine (6.1 ml, 34.86 mmol) were added to a solution of methyl (4-bromo-3,5-dimethylphenyl)carbamate (900 mg, 3.48 mmol) in anhydrous DMA (17.5 ml, 0.2 M). After irradiation with microwaves at 170° C. for 30 minutes, water was added to the reaction solution, followed by extraction with ethyl acetate. The organic phase was sequentially washed with water and saturated brine and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give 3-(4-bromo-3,5-dimethylphenyl)-5,5-dimethylimidazolidine-2,4-dione (304 mg, 28%)
