2-Ethyl-3-[(R)-2-phenyl-butanamido]-quinazolin-4(3H)-one monohydrate.

ABSTRACT: In the title compound, C20H21N3O2·H2O (EQR·H2O), the quinazoline ring system forms dihedral angles of 53.1?(1) and 85.6?(1)° with the phenyl ring and the amide link, respectively. In the crystal, O-H?O hydrogen bonds link two EQR and two water mol-ecules into a centrosymmetric R 4 (4)(18) ring motif. N-H?O hydrogen bonds further link these hydrogen-bonded fragments into columns extending in [010].

In the title compound, C20H21N3O2·H2O (EQR·H2O), the quinazoline ring system forms dihedral angles of 53.1 (1) and 85.6 (1)° with the phenyl ring and the amide link, respectively. In the crystal, O-H⋯O hydrogen bonds link two EQR and two water mol-ecules into a centrosymmetric R 4 (4)(18) ring motif. N-H⋯O hydrogen bonds further link these hydrogen-bonded fragments into columns extending in [010]. ...[more]
