Descripción
Sumario:In the title compound, C(11)H(10)N(2)O(2), a potential inhibitor of the cyclo­oxygenase-2 isoenzyme, the pyrazoline ring exists in a flat-envelope conformation while the puckering of the central oxazine ring is more severe. As a result, the mol­ecule as a whole is non-planar. The formal sp (3) pyrazoline N atom is sp (2) hybridized, with the lone-pair electrons delocalized through conjugation with the carbonyl group rather than the double bond of the pyrazoline ring.
