Abstract: In the title compound, C19H16N4O3, the stereocenter has an L configuration; L-tryptophan methyl ester hydro­chloride being used as a starting material. The indole ring system and the pyridine ring are inclined to one another by 13.55 (14)°. In the crystal, adjacent mol­ecules are linked via N-H...O hydrogen bonds, forming chains propagating along the c-axis direction.
