Some 3,4-dimethoxybenzyl ketones are prepared by the action of different acid anhydrides on homoveratric acid. From these ketones the following 5,5-substituted hydantoms are synthesized: 5-methyl-5-(3',4'-dimethoxybenzyl)-hydantoin, m.p. 240-1°;5-ethyl-5-(3',4'-dimethoxybenzyl)-hydantoin, m.p. 224-225.5°;and 5,5-di-(3',4'-dimethoxy-benzyl)-hydantoin, m.p. 293-4.5. The infrared spectra of the last two compounds are recorded.
