Reaction Steps
Process for the preparation of cericlamine which consists: i) in arylating methacrylic acid with the diazonium chloride of 3,4-dichloroaniline, to obtain (+/-)2-chloro-3-(3,4-dichlorophenyl)-2-methylpropionic acid, ii) in aminating the acid with dimethylamine, to obtain (+/-)3-(3,4-dichlorophenyl)-2-dimethylamino-2-methylpropionic acid, or an alkaline metal salt thereof, iii) in esterifying the amino-acid or its salt, then, iv) in reducing the ester by a metal or organometal hydride to obtain (+/-)3-(3,4-dichlorophenyl)-2-dimethylamino-2-methyl-propan-1-ol.
