    摘要: 2-(o-Hydroxyphenyl)-pyrrole and a process for its preparation, wherein o-benzyloxybenzoic acid allylamide is reacted with phosgene in an inert solvent, the resulting imide-chloride is cyclized in the presence of a strong sterically hindered base and the benzyl protective group is then removed by hydrogenolysis.2-(o-Hydroxyphenyl)-pyrrole is a valuable intermediate for the synthesis of drugs. In particular, alkylamino-hydroxypropyl ethers thereof can, because of their .beta.-sympatholytic actions, be used for the treatment of coronary cardiac diseases, cardiac arrhythmias and hypertonia.
