Reaktionsschritte
A solution of 300 mg of 5-benzoyl-6-methylthio-1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylic acid in 5 ml of isoamyl alcohol is saturated with hydrogen chloride. After 24 hours, the excess alcohol is distilled off in vacuo and the residue purified by chromatography on alumina, to yield isoamyl 5-benzoyl-6-methylthio-1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylate.
