Abstract
Method of obtaining teofylin-acetate from p-hidroxy-N- (1-methyl-2-phenoxyethyl) norefedrine "characterized in that the compound p-hydroxy- α (1'-methyl-2-phenoxyethylamino) propiophenone, it is subjected to a catalytic reduction, until the attainment of p-hydroxy-N- (1-methyl-2-phenoxyethyl) norofedrine, which, in the presence of the theophylline-7-acetic acid, and according to the following reaction scheme: ** (see formula) ** Promotes the obtaining of theophylline-7-acetate of p-hydroxy-N- (1-methyl-2-phenoxyethyl) norephedrine, according to the following chemical structure: (see formula) (Machine-translation by Google Translate, not legally binding)
