Trifluoroacetylation of Methylpyridines and Other Methylazines: A Convenient Access to Trifluoroacetonylazines
摘要:
Treatment of methyl substituted azines, such as pyridine, pyrimidine, quinoline, oxazole, benzoxazole, benzimidazole, and benzothiazole, with trifluoroacetic anhydride in the presence of pyridine at room temperature gave the corresponding trifluoroacetonyl substituted azines in good yields.
