A New Synthesis of Pyrazolothiazoles

An efficient synthesis of pyrazolothiazoles (6) was achieved by treatment of N-(4-amino-5-pyrazolyl)thiocarboxamides (4) with sodium nitrite in acidic medium followed by irradiation with uv light.

Synthesis of Pyrazolothiazoles

Several 5-substituted 1-phenylpyrazolothiazole derivatives have been synthesized by reaction of 5-amino-3-methyl-1-phenylpyrazole-4-thiol with different reagents.
