Indazole compounds of the formula ##STR1## wherein R.sub.1 is hydrogen or lower alkyl, R' is hydrogen or acyl, e.g., alkanoyl, and R.sub.2 is benzyl or a radical of the general formula ##STR2## in which X is a reactive residue and Y is hydroxyl or X and Y together represent oxygen and, when R' is an acyl radical, R.sub.2 can also be hydrogen: Are valuable intermediates for the preparation of pharmacologically active compounds, e.g., adrenergic .beta.-receptor active 3-indazolyl-(4)-oxy-propan-2-ol-amines.
式为##STR1##的吲哚类化合物,其中R.sub.1是氢或较低的烷基,R'是氢或酰基,例如烷酰基,R.sub.2是苄基或一般式##STR2##中的基团,其中X是反应性残基,Y是羟基或X和Y一起代表氧,当R'是酰基基团时,R.sub.2也可以是氢:对于制备药理活性化合物,例如肾上腺素β-受体活性的3-吲哚基-(4)-氧基-丙醇胺,这些吲哚类化合物是有价值的中间体。
