A novel method for the synthesis of 6,12-dihydro-2-methylindolo[2,3-b]carbazol-6-ones was developed from 1-oxo-2,3,4,9-tetrahydro-1H-carbazol-1-one through methyl 6-methyl-2-(1-oxo-2,3,4,9-tetrahydro-1H-carbazol-2-yl)oxoacetate in good yields. This method provides an alternative path for the synthesis of this product using 2-hydroxy methylene-2,3,4,9-tetrahydro-1H-carbazol-1-one.
