| titleOfInvention | PROCEDURE FOR PREPARATION OF 5-SUBSTITUTED DERIVATIVES OF 5- (3'4 ', 5', -TRIMETHOXYBENZYL) -HYDANTOIN |
| abstract | A process for the preparation of 5-SUBSTITUTED DERIVATIVES OF 5- (3'4 ', 5', -TRIMETHOXYBENZYL) -HYDANTOIN, of general formula I, in which R has the meaning of a methyl, ethyl, n-propyl, n-butyl or allyl radical, that the 2-substituted 2- (3 ', 4', 5'-trimethoxybenzyl) -malondiamide derivatives of general formula II, in which R has the above meaning, are dissolved in a solution of sodium hypochlorite and sodium hydroxide, the resulting reaction mixture is heated to 3-5 hours at 50-70 C, then cooled to room temperature, the pH was adjusted to 6-7 by the addition of dilute hydrochloric acid, the precipitated crystals were filtered off with suction and recrystallized from alcohol, ethanol or isopropanol. |
