title: 5'-Methyl-sulfanyl-4'-oxo-7'-phenyl-3',4'-dihydro-1'H-spiro-[cyclo-hexane-1,2'-quinazoline]-8'-carbonitrile dimethyl-formamide monosolvate.
abstract: In the title compound, C(21)H(21)N(3)OS·C(3)H(7)NO, the carbonitrile mol-ecule is built up of two fused six-membered rings and one six-membered ring linked through a spiro C atom. The 1,3-diaza ring adopts an envelope conformation and the cyclo-hexane ring adopts a chair conformation. The dihedral angle between the aromatic rings is 46.7 (3)°. In the crystal, the components are linked by N-H⋯O hydrogen bonds.
