Reaction Steps

54.6 5-methyl-5-phenethyl-hydantoin (0.25 Mol) are reacted with 30 g sodium hydroxide (0.75 Mol) and 150 ml water for 3.5 hours in an autoclave at an oil bath temperature of 180° C. After cooling, 350 ml H2O are added and the clear, light brown solution adjusted with hydrochloric acid to pH 7.0. The white precipitate is suctioned off, washed with 20 mg H2O and dried in a vacuum drying cabinet at 65° C. The product is recrystallized twice from water.
