An efficient route to synthesize 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (6) and 2,4-dichloro-7H- pyrrolo[2,3-d]pyrimidine (10) starting from diethyl malonate in five steps with the total yields of 45.8% and 44.8% was disclosed in the presented paper. The chemical structures of the objective products as well as the related intermediates were confirmed.

Key words: diethyl malonate, α-alkylation, K2OsO4, SNAr/cyclization
