Abstract: A method for preparing 2-furylpyrimidine derivs.  of  formula (I) and (II) comprises sililating a cpd.  of  formula  (III),  and reacting it with 2-acetoxy tetrahydrofurane of formula (IV) in  an organic solvent in the presence of cesium chloride. In (I), X =  O or S; R1 and R2 each = O, NH2, F, Br, CH3 or H. In (II), X = O; R1 and R2 each = O, H, F or CH3. In (III), X = O or S; R1 and R2 each = O,  NH2,  F,  Br,  CH3  or  H.  Pref.  the  organic  solvent  is acetonitrile. The molar ratio of cesium chloride to the pyrimidine cpd. of  formula (III)  is  7-12  %.  Cpds.  (I)  and  (II)  have anticancer activity.
