Abstract

The invention comprises 1-phenyl-2:3-dimethyl - 4 - O:O - diphenyl phosphorylamidopyrazolone and its preparation by treating 1-phenyl - 2: 3 - dimethyl - 4 - amino - pyrazolone with a diphenyl halogenophosphate. The reaction is preferably carried out in a solvent such as benzene and in the presence of a hydrogenhalide binding agent such as triethylamine.
