Reaction Steps

To a solution of 4-(2-fluoro-phenyl)-1H-pyrimidin-2-one (375 mg, 1.97 mmol) in dry DMF (50 ml), 60% NaH (103 mg, 2.56 mmol) was added portionwise. After heating the mixture at 100° C. for 1 hour, tert-butyl-(4-iodo-butoxy)-dimethyl-silane (664 μl 2.56 mmol) was added at room temperature and the mixture was stirred overnight. Water was added and the mixture extracted with diethyl ether; the organic layer was dried (Na2SO4), filtered and evaporated. The residue was purified by flash chromatography with petroleum ether-ethyl acetate (1-1) to give 370 mg of the title compound as a yellow solid (50% yield).
