The title compds. I≮n=1,2,3; R1=H, aliph. acyl,benzoyl, R3C6H4CO-; R2=H, C1-C4 aliph. alkyl, C2-C5 aliph. acyl, benzoyl, R4C6H4CO-; R3=H, Me; R4=H, Me≉and their pharmaceutically acceptable salts, which showed bronchodilating, α-spasmolytic, and uterus-relaxing activity in tests on animals, were prepd. Thus, 3.0g 1,1-dimethyl -3- (2-methoxyphenyl)propyl amine in 40mL EtOH was treated with 4.0g 4-benzyloxy- phenyloxalate and reduced to give 1-(4-hydroxyphenyl)-2-≮1,1-dimethyl-3-(2-meth- oxyphenyl)propylamino≉-ethanol.
