摘要

1-Isopropylamino-2-hydroxy-3-(2'-isopropoxy-phenoxy)-propane, pharmaceutically used in heart and circulatory disorders. Cpds. of formula:- is prepared by cleaving off from 2-hydroxyl group of 1-isopropylamino-2-hydroxy-3-(2'-isopropoxy-phenoxy)-propane a residue that may be cleaved off by hydrolysis or hydrogenolysis, such as alpha-arylalkyl residue, e.g. benzyl, or tert. butoxycarbonyl or lower alkanoyl.
