The crystal structure of 3-Amino-2-(4-methylphenylamino)quinazolin-4(3H)-one (TNT2) is reported. TNT2 is monoclinic, space group C2/c with a = 23.127(5), b = 7.845(2), c = 14.625(3) A and beta=93.58 (3)°. The structure was refined by full matrix least square methods using SHELX93-97program to Rl = 0.051. Torsion angles calculation found that the three rings are-planar within the Experimental error. The phenyl ring connected to C2 is deviated slightly from the plane of quanozlin ring, this feature is different from that found in the molecules of 3-(Diacylamino)quinazolin-4(3H)-ones. Intermolecular hydrogen bond is found between N1...H18B with a value of 2.710 A.
