1-H-Pyrrole-2-carboxylic acid [2-(naphthalen-1-ylamino)-ethyl]-amide has been synthesized and characterized. Its crystal is of monoclinic, space group P21/n with a = 5.930(6), b = 12.144(13), c = 20.10(2) , β = 95.709(17)°, V = 1441(3) , Z = 4, C17H17N3O, Mr = 279.34, Dc = 1.288 g/cm3, F(000) = 592, μ(MoKα) = 0.083 mm-1, S = 1.019, R = 0.0473 and wR = 0.1181 for 1713 observed reflections with I > 2σ(I). X-ray diffraction reveals that two molecules of the title compound form a dimer through a pair of N–H…O hydrogen bonds.
