Novel hydroxyphenylaminobenzenealkanols, useful as antiasthmatic agents, are of the formula ##STR1## wherein R is hydrogen, lower-alkyl, lower-alkoxy or halo; R' is hydrogen or lower-alkyl; R" is hydrogen, lower-alkyl or halo; and Y is C.sub.n H.sub.2n wherein n is 1-2. The compounds are prepared by de-etherification of the corresponding phenol alkyl or benzyl ethers; by reduction of the corresponding benzoic acids or esters thereof; or by reduction of ketones wherein --Y--OH is replaced by --COCH.sub.3.
具有抗哮喘作用的新型羟基苯胺烷醇化合物的化学式为##STR1##其中R为氢、低碳基、低氧基或卤素;R'为氢或低碳基;R"为氢、低碳基或卤素;Y为C.sub.n H.sub.2n,其中n为1-2。该化合物可通过对应苯醚或苄基醚的去醚化反应制备;对应苯甲酸或其酯的还原反应制备;或者通过取代--Y--OH的酮的还原反应制备。
