Reaction Steps

4.56 g (40 mmol) of 3-methyl-hydantoin, 30 ml of acetic acid, and 2.0 ml (40 mmol) of bromine were mixed at room temperature. The reaction mixture was then vigorously stirred at a temperature of 40° C. for 2 hours. The reaction mixture was then allowed to cool to room temperature. To the reaction mixture was then added 60 mmol of anisole. The reaction mixture was then allowed to undergo reaction at a temperature of 100° C. for 6 hours. The resulting precipitate was recovered by filtration, washed with water, and then dried to obtain 4.22 g (yield: 48%) of 5-(p-methoxyphenyl)-3-methyl-hydantoin.
