Ethyl 5-Ethoxy-3-methyl-1H-indole-2-carboxylate

The title compound, C₁₄H₁₇NO₃, having an ethoxy-carbonyl group at C2, serves as an important precursor in the synthesis of fused-indole heterocycles of biological importance. The indole moiety is planar and it forms dihedral angles of 2.3 (1) and 3.9 (1)° with the ethoxycarbonyl group at C2 and the ethoxy group at C5, respectively. The centrosymmetrically related molecules are held together by hydrogen bonds across a centre of symmetry and form dimers.
