Article abstract of DOI:10.1107/S0108270195000837

Knowledge of the conformation at the amide N atom of N-3-methoxyphenyl-2-(5-methoxyindole)carboxamide, C17H16N2O3, and N-methyl-N-phenyl-2-(5-methoxyindole)carboxamide, C17H16N2O2, allows an interpretation of the 1H NMR behavior of the two compounds.The structures and conformations of the two molecules are compared.
