    摘要: .alpha.-Aminomethyl-4-hydroxy-3-methylsulfonyl benzyl alcohols having .beta.-adrenergic antagonist activity are prepared generally from 4-benzyloxy-3-methylsulfonylacetophenone by, for example, bromination and treatment of the resulting .alpha.-bromo derivative with an N-benzyl secondary amine, followed by catalytic hydrogenation to remove protective benzyl groups and reduce the ketone moiety.

    摘要: N,N'-Bis[2-(3-substituted-4-hydroxyphenyl)-ethyl or-2-hydroxyethyl]-polymethylenediamines having .beta.-adrenergic stimulant activity particularly as selective bronchodilators, are prepared generally by condensation of an N-benzylphenethylamine with a polymethylene dihalide or by reaction of an .alpha.-bromoacetophenone with an N,N'-dibenzyl-polymethylenediamine, with further operations depending on the nature of the 3-substituent, and subsequently hydrogenating catalytically with for example palladium-on-carbon. The key intermediates are also part of the invention.
