Synthesis of new furo[2,3-d]pyrimidines and pyrimido[4′,5′:4,5] furo[2,3-d]pyrimidines

Sodium salt of 4-hydroxy-6-methyl-2-phenylpyrimidine-5-carbonitrile (3) was subjected to alkylation with different α-halo compounds, where the corresponding O-alkylated products 4a-g were obtained. Ring closure of the O-alkylated product 4a-c performed using sodium ethoxide in refluxing ethanol afforded furo[2,3-d]pyrimidines 5a-c. The latter compounds on reaction with a variety of reagents gave other new furopyrimidines as well as a number of furodipyrimidines.
