Abstract

A novel method for the preparation of substituted 2-pyrimidinyl- and s-triazinyl-formamide oximes is described. Heterocyclic amines 1 are first converted with trisformaminomethane, as the most powerful formylating agent, into formylamino derivatives 3. These give by treatment with hydroxylamine the corresponding formamide oximes 4 in yields up to 95%.
