Procedure

2-Chloro-6-iodo-4-morpholinothieno[3,2-d]pyrimidine (150 mg), 2-oxazolidinone (103 mg), potassium phosphate tribasic (250 mg), copper iodide (7 mg), 4 μL of N,N-dimethylethylenediamine in 2 mL of 1,4-dioxane was heated to 100° C. for 15 hr. The reaction mixture was evaporated and the residue was diluted with ethyl acetate (50 mL), washed with brine (30 mL), dried over MgSO4, filtered and evaporated. The crude product was purified on reverse phase HPLC to give 46 mg of 3-(2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl) oxazolidin-2-one.
