A fischer-indole approach to pyrrolo[2,3-d]pyrimidines
Taylor, Edward C.,Hu, Baihua
, p. 323 - 338 (2007/10/03)
Several new 5,6-disubstituted pyrrolo[2,3-d]pyrimidines have been prepared by thermolysis of ketone hydrazones of 2-amino-6-hydrazino4(3H)-oxopyrimidine (8) (the Fischer-Indole Synthesis).
