5'-Methyl-4'-oxo-7'-phenyl-3',4'-dihydro-1'H-spiro-[cyclo-hexane-1,2'-quinazoline]-8'-carbonitrile.

ABSTRACT: The title compound, C(21)H(21)N(3)O, was obtained by cyclo-condensation of 3-amino-5-methyl-[1,1'-biphen-yl]-2,4-di-car-bo-nitrile with cyclo-hexa-none. The six-membered 1,3-diaza ring assumes an envelope conformation [with the flap atom displaced by 0.511?(7)?Å from the plane through the other ring atoms] and the cyclo-hexane ring displays a chair conformation. The dihedral angle between the aromatic rings is 42.61?(7)°.In the crystal, the mol-ecules form hydrogen-bonded bands along [011].
