Procedure
To a mixed solution of 6-chloro-3-methyl-1-(3-(trifluoromethyl)phenyl)pyrimidin-2,4(1H,3H)-dione (prepared in Reference Example 56) (149 mg) in THF (5 ml) and N-methylpyrrolidone (0.5 ml) were added under nitrogen atmosphere iron(III) acetylacetonate (26 mg) and isopropylmagnesium chloride (2M THF solution, 1 ml), and the resulting mixture was stirred at room temperature for two and a half hours. The reaction solutions were added to 1N hydrochloric acid, and the resulting mixture was extracted with ethyl acetate (20 ml×2). The organic layer washed with saturated saline (20 ml), dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate) to afford 6-isopropyl-3-methyl-1-(3-(trifluoromethyl)phenyl)pyrimidin-2,4(1H,3H)-dione (53 mg).
