Dimethyl 6-Amino-1-methyl-9H-carbazole-2,3-dicarboxylate

Abstract

The title compound (2) was prepared in high yield by catalytic transfer hydrogenation of the 6-nitro precursor (1), using hydrazine hydrate as the hydrogen source. Under the conditions employed, the ester groups remain unaffected. The new compound was fully characterised by elemental analysis, 1H-NMR, 13C-NMR, MS and HRMS data.
