compounds, where the corresponding O-alkylated products 4 a - g were obtained. Ring closure of the O-alkylated product 4 a - c performed using sodium ethoxide in refluxing ethanol afforded furo[2,3-d]pyrimidines 5 a - c . The latter compounds on reaction with a variety of reagents gave other new furopyrimidines as well as a number of furodipyrimidines.
