1-(2,4-Dinitrophenyl)-3-methyl-5-pyrazolon-4-oxime (I) reacts with benzylamine to give 1-(2,4-dinitrophenyl)-3-methyl-5-phenyl-1H-pyrazolooxazole (II).Its structure has been established by another route involving reaction of I with benzyl cyanide in the presence of sodium ethoxide. 1-(2,4-Dinitrophenyl)-3-methyl-1H-pyrazolooxazole (III) has been prepared by the interaction of I with methyl iodide in the presence of K2CO3.Its structure has been elucidated by an unambiguous synthesis involving reaction of diazomethane with I.
