4-Functionally Substituted 3-heterylpyrazoles: XII. 4-Chlorothieno[2,3-c]pyrazole-5-carbonyl Chlorides
摘要:
3-(4-Pyrazolyl)acrylic acids reacted with excess thionyl chloride in the presence of benzyltri-ethylammonium chloride affording 4-chlorothieno[2,3-clpyrazole-5-carbonyl chlorides which were converted into the corresponding acids, esters, and amides.
