3-(2-Amino-eth-yl)-2-[4-(trifluoro-meth-oxy)anilino]quinazolin-4(3H)-one

In the title compound, C(17)H(15)F(3)N(4)O(2), the dihedral angle between the trifluoro-meth-oxy-substituted benzene ring and the pyrimidinone ring is 45.1 (5)°, while that between the fused benzene ring and the pyrimidinone ring is 0.67 (1)°. Part of one of the benzene rings and its trifluoro-meth-oxy substituent are disordered over two positions of approximately equal occupancy (0.51:0.49). Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds contribute to the stability of the crystal structure. A weak intra-molecular C-H⋯F contact is also found. In addition, π-π stacking inter-actions, with centroid-centroid distances in the range 3.673 (6)-3.780 (8) Å, and weak C-H⋯π inter-actions are also observed.
