A new synthetic route to triaryl pyrrolo[2,3-d]pyrimidines from common 4,6-dichloropyrimidine has been developed. The triarylated compounds are synthesized by three cross-coupling reactions using three different catalysts. The introduction of a C-6 aryl group was achieved in a two-step process under Sonogashira conditions [Pd(dba)2/CuI] followed by intramolecular cyclization, and application of Suzuki-Miyaura conditions [Pd(PPh3)4; PdCl2(PPh3)2] led to C-4 and C-5 diarylation. This sequence allows a flexible synthetic approach to highly arylated pyrrolopyrimidines containing different aryl groups.

A novel, general, and efficient one-pot sequential reaction toward a variety of 4-aminated-6-arylpyrrolo[2,3-d]pyrimidines from 5-alkynylpyrimidines has been developed. Microwave-assisted metal-free intramolecular cyclization and amination provided moderate to excellent yields of 4-aminated pyrrolo[2,3-d]pyrimidines in short reaction times. This method avoids the use of metal-catalyst and expensive additives and was shown to tolerate amines and anilines.
