Formylation of 1,2,3,4-tetrahydro-2,4,5-trimethylpyrrolo-1-2,c]pyrimidine. Its conversions to the 7-formyl derivative with opening of the tetrahydropyremidine ring

We have optimized the method for obtaining 1,2,3,4-tetrahydro-2,4,5-trimetkylpyrrolo[1,2-c]pyrimidine. We carried out the reactions of quaternization, forinylation, and opening of the tetrahydropyrinddine ring of its 7-formyl derivative and the oxime of this carbonyl compound.Russian University of International Friendship, Moscow 117923.
