반응 단계
A solution of 148 g. of 5-p-methoxybenzyl hydantoin and 188 g. of sodium hydroxide in one liter of water is heated at reflux for 25 hours. The solution is cooled and made acid to pH 1 with concentrated hydrochloric acid. The formed solid is separated by filtration, washed with water and dried to give the above named compound, mp. 255° C. dec.
