Методика

When 6,7-dichloro-2-(i-propyl)-2-methyl-1-hydroxyindan-5-ylacetamide, 6,7-dichloro-2-ethyl-2-methyl-1-hydroxyindan-5-ylacetamide, and 6,7-dichloro-2-ethyl-2-(n-propyl)-1-hydroxyindan-5-ylacetamide are utilized as starting materials in the diethyloxalate/potassium t-butoxide reaction there are obtained 4-[6,7-dichloro-2-(i-propyl)-2-methyl-1-hydroxyindan-5-yl]-3-hydroxy-3-pyrroline-2,5-dione, 4-(6,7-dichloro-2-ethyl-2-methyl-1-hydroxyindan-5-yl)-3-hydroxy-3-pyrroline-2,5-dione, and 4-[6,7-dichloro-2-ethyl-2-(n-propyl)-1-hydroxyindan-5-yl]-3-hydroxy-3-pyrroline-2,5-dione.
