Abstract
Process for the preparation of a dialkoylaminoalkoxy derivative represented by the formula ** (See formula) ** and named 1-benzyl-3- (3-dimethylamino-propoxy) 1H-indazole or benzidamine, said process characterized by reacting N-benzyl anthranilic acid with sodium nitrite in an acid medium, then reducing the nitrosated derivative obtained with sodium hydrosulfite. and finally treating with 3-dimethylamino-propyl chloride the 1-benzyl-3-hydroxy-1H-indazole formed.
