title: 3-(2-Amino-ethyl)-2-anilinoquinazolin-4(3H)-one methanol hemisolvate.
abstract: The title methanol hemisolvated quinazolin-(3H)-one, C(16)H(16)N(4)O·0.5CH(3)OH, has an anilino substituent in the 2-position and an amino-ethyl substituent in the 3-position of the planar fused-ring system (r.m.s. deviation = 0.019 Å). The anilino N atom donates an intramolecular hydrogen bond to the amino-ethyl N atom. The mol-ecule and the solvent methanol mol-ecule are linked by N-H⋯N, N-H⋯O and O-H⋯O hydrogen bonds. The methanol mol-ecule is disordered over two equally occupied positions about a twofold rotation axis.
