U.S. US 4010158 1 Mar 1977, 4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C093-06. NCL: 260253000. PRIORITY: DE 67-92594 18 May 1967. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) 1-(2-Ethynylphenoxy)-2,3-epoxypropane, obtained from 2-ethynylphenol and epichlorohydrin, was treated with RNH2 (R = Me3C, EtCHMe) in MeOH or EtOH to give o-(CH.tplbond.C)C6H4OCH2CH(OH)CH2NHR (I; R as before) which were converted to their HCl salts. The compds. prepd. exhibit .beta. 13952-84-6 and 5101-44-0 which are cas registry numbers of chemicals are mentioned.-adrenolytic and hypotensive activities in warm blooded animals, e.g., I.cntdot.HCl (R = Me3C) at a dose of 30 mg/60 kg body wt. of animal produced very good .beta.-adrenolytic effect. .
