1-(N-Arylthiocarbamoyl)amidino-3,5-dimethyl Pyrazoles-Preparation and Use in Heterocycle Synthesis
摘要:
On reaction with alpha-haloketones or hydrazine, 1-(N-arylthiocarbamoyl)amidino-3,5-dimethylpyrazoles (I) afford 2,4-diaminothiazoles and 3,5-diamino-1,2,4-triazoles in good yield. A convenient route to 1 is also reported.
