Notes:
The crystal structure of the title compound contains four 2,4-diamino-5-methyl-6-[(3,4,5-trimethoxyanilino)methyl]quinazoline molecules, two dimethyl sulfoxide molecules and three water molecules in the asymmetric unit, i.e. 4C19H23N5O3·2C2H6OS·3H2O. All four quinazoline molecules adopt trans,gauche conformations. An extensive hydrogen-bond network involving N...N base-pairing interactions, as well as the dimethyl sulfoxide and water molecules, stabilizes the crystal structure.
