Abstract
Method of synthesis of 1-methyl-5 p-toluoylpyrrol-acetate, sodium, characterized in that the starting point is 1-methyl-2-pyrrolacetonitrile, which is treated with dilute sulfuric acid and passes to 1-methyl-2- pyrrolacetamide, which by reaction with p-tolnico anhydride carried out in a completely anhydrous medium, dissolving petroleum ether as solvent and using anhydrous iron trichloride as catalyst, gives a mixture of two isomers, 1-methyl-5 p-toluoyl-pyrrol- 2-acetamide, taking into account that the reaction vessel must be cooled externally so that the temperature does not exceed 5-10º, proceeding to the decomposition of the excess of reactants at the end of the reaction with the addition of very cold concentrated hydrochloric acid.
