Abstract
The title reaction produces 6-amino-3,3’-dimethyl-5’-oxo-1,1’-diphenylspiro[pyrano[2,3c]pyrazole -4(1H),4’-[2]-pyrazoline]-5-carbonitrile 4, the structure of which has been determined by X-ray crystallography. It crystallizes in the orthorhombic space group Pna21, with two independent molecules in the asymmetric unit.
