Chlorination of 3-fluoro-2-methyl-aniline with N-chloro-succinimide gave one major regioisomer whose structure was determined by X-ray crystallography. The product was found to have cocrystallized with succinimide, giving the title compound, C(7)H(7)ClFN·C(4)H(5)NO(2). The crystal structure is stabilized by N-H⋯O hydrogen-bonding and π-π stacking inter-actions with a centroid-centroid distance ...

3-Methyl-5-chloro-1-phenylpyrazol and its derivatives were prepared by the reaction with 3methyl -1-phenylpyrazol-5-one, phosphorous oxytrichloride and N-N dimethyl aniline respectively using catalyst. These compounds were further treated with alcohols and sodium hydroxide to form ether linkage. Ethyl acetoacetate reacted with phenylhydrazine at reflux temprature to give 3-methyl-1phenylpyrazol...
