Abstract
Method of production of an optically active compound of the formula ** (See formula) ** and acid addition salts thereof, characterized in that those compounds of the formula II and the acid addition salts thereof, whose configuration of the 1- (4-hydroxyphenyl) -2-aminopropanol radical corresponds to the of normal levogyral ephedrine and the configuration of the radical 1-methyl-3-phenylpropylamine corresponds to that of the levorotatory hydrochloride of 1-methyl-3-phenyl-propylamine, base having a melting point of 123 to 124.5º C and the salt of the sulfamic acid has a value of (α) 23D of about -3º, are produced by methods already known per se for the production of similar compounds and by analogous methods.
