Abstract
Procedure for obtaining a pirrol derivative. Compound (II) in which r is alkyled (preferably methyl or ethyl) with bromine in glacial acetic acid, followed by spilling on a sodium sulfur aqueous solution is reactioned. The intermediate obtained is isolated, which in dissolution of an ether is reacted with magnesium in the presence of iodine as a catalyst and then as p-chlorobenzaldehido, followed by ice addition and after sulfuric acid to a concentration understood between 5 and 50%, extraction with an immisible solvent addition of an alkaline carbonate and another series of operations. Compound is obtained (I). (Machine-translation by Google Translate, not legally binding)
