ABSTRACT:
.alpha.-Aminoalkyl-4-hydroxy-3-alkylsulfonylmethylbenzyl alcohols having .beta.-adrenergic stimulant activity, particularly as selected bronchodilators, are prepared from 4-hydroxyphenones by conversion to a 3-alkylsulfonylmethylphenone, bromination of these phenones and treatment of the resulting .alpha.-bromo derivatives with an N-benzyl secondary amine, followed by catalytic hydrogenation to remove the benzyl groups and reduce the ketone moiety.
