Abstract
Process for the obtaining of 1- (4-amino-3,5-dichlorophenyl) -2-terbutilamino ethanol from formula (I) and its salts from formula (II), where x is an organic or inorganic anion. Is to do reaction 2.6 dicloroanilina of formula (III) with bromine, obtaining the 2.6 dicloro-4 bromo-anilina, that is isolated solidly. By addition of magnesium chips to this compound, in etherna solution, the bromide of 3,5-dichloro-4 aminofenil magnesio is obtained, which is reacted with the 2-terbutilamino acetaldehido de formula (IV), obtained by acid hydrolysis and posterior neutralization the compound of formula (I). By addition to this of acids xh the salts of formula (II) are obtained. *formula* (Machine-translation by Google Translate, not legally binding)
