The title compound, N-(2-(1H-indol-3-yl)ethyl)-2-nitroaniline (C16H15N3O2, Mr=281.31), has been synthesized by the multicomponent reaction of milder Ullmann, and its structure was characterized by 1H NMR, 13C NMR, IR, H RMS (ESI) and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group I2/c with a=15.0212(10), b=9.4911(6), c=20.3075(13)Å, β=100.776(7)°, V=2844.1(3)Å3, Z=8, Dc=1.314 g/cm3, F(000)=1184.0, μ=0.089 mm-1, the final R=0.0574 and wR=0.1688 for 1701 observed reflections (I>2σ(I)). X-ray analysis indicates three major N(2)-H(2)…O(2), C(13)-H(13)…O(2), N(2)-H(2)…N(3) hydrogen bonds and π-π stacking interactions in the crystal structure. The preliminary biological test shows that the title compound has a good antitumor activity against A549 in vitro with the IC50 value of 35 μmol/L.
