Process for preparing N- (1-benzo [b] thien-2-ylethyl) -N-hydroxyurea |
| abstract |
A method for preparing N- (1-benzo [b] thien-2-ylethyl) -N-hydroxyurea of formula I by reacting 1- (benzo [b] thien-2-yl) -ethanol of formula II with a hydroxy acid of formula III in organic solvents, organic acids, mixtures thereof or a mixture of water under catalysis with strongly acidic cation exchangers or various hydrogensulfates. The method of isolating the compound of formula I prepared as above from the reaction mixture by neutralization in the presence of organic acids. |
