Oxalylhydrazides as oxidation products of analgesic pyrazolinones

In contrast to antipyrine (1a) and isopropylantipyrine (1b) the amino-substituted pyrazolinones 4-aminoantipyrine (1d), 4-methylaminoantipyrine (1e), 4-isopropylaminoantipyrine (1f) and dipyrone (1g) as well as 4-hydroxyantipyrine (1e) can be cleaved into

METHYLATION OF N-PHENYL-N'-ACETYLHYDRAZINE WITH DIMETHYL SULFATE

The reaction of N-phenyl-N'-acetylhydrazine with dimethyl sulfate in benzene in the presence of a 40percent solution of sodium hydroxide leads to a mixture of N-methyl-N-phenyl-N'-acetylhydrazine (45percent), N,N'-dimethyl-N-phenyl-N'-acetylhydrazine (31percent), and N'-methyl-N-phenyl-N'acetylhydrazine (24percent).The dimethyl derivative is formed through the methylation of N-methyl-N-phenyl-N'-acetylhydrazine by dimethyl sulfate, whereas the other isomer does not react under these conditions.
