1-Phenyl-3-methyl-5-pyrazolone-4-oxime reacted with benzylamine, methylamine, methyl- and ethyl iodides to give 3-methyl-1,5-diphenyl-1H-, 3-methyl-1-phenyl-1H- and 3,5-dimethyl-1-phenyl-1H-pyrazolooxazoles I,II.The structure of I was elucidated authentically through other routes by interaction of 1-phenyl-3-methyl-4,5-dioxopyrazolone with benzylamine and/or benzaldehyde and ammonium acetate.Various 3-methyl-5-aryl-1-phenyl-1H-pyrazolooxazoles IV were synthesized by the reaction of 4,5-dioxopyrazolone with aromatic aldehydes in the presence of ammonium acetate.Also, the structure of I was elucidated authentically via other routes by the reaction of 1-phenyl-3-methyl-4-imino-5-pyrazolone with each of benzylcyanide, benzylamine, benzaldehyde and benzalaniline.
