Procedure

To a stirred solution of N-(3,5-dimethyl-phenyl)-N-(5-ethyl-2,6-dioxo-1,2,3,6-tetrahydro-pyrimidin-4-yl)-acetamide (109) (602 mg, 2 mmol) anhydrous powdered K2CO3 (276 mg, 2 mmol), and lithium iodide (268 mg, 2 mmol) in DMF (6 mL), was added 1-methanesulfonyl-trans-2-butene (283 μL, 2.4 mmol). After stirring for 13 hr., the reaction mixture was diluted with ether, washed with water, dried with MgSO4, filtered, and evaporated in vacuo. The residue was purified by silica gel column chromatography (eluent, ethyl acetate:hexane (1:1)) to afford 291 mg (40%) of a white solid. m.p. 218-220° C.; m/z (EI) 355(M+).
