2-methyl-1-phenylpropan-2-yl 2-((4R,6S)-6-((E)-2-(4-(4-fluorophenyl)-6-isopropyl-2-(N-methylmethylsulfonamido)pyrimidin-5-yl)vinyl)-2,2-dimethyl-1,3-dioxan-4-yl)acetate (15.38 g) prepared in Example 19 was dissolved in tetrahydrofuran (80 ml) and a 0.1M hydrochloric acid aqueous solution (19.21 ml) was added thereto, followed by stirring for 24 hours while heating to 40° C. The reaction liquid was cooled to room temperature and a 0.5M sodium hydroxide aqueous solution (81 ml) was added thereto over 5 minutes, followed by stirring for 4 hours. Ethyl acetate (250 ml) and purified water (250 ml) were added to the reaction liquid, and the organic layer was separated, washed with saturated sodium chloride (150 ml), dried over anhydrous sodium sulfate, filtered, and then concentrated under reduced pressure to give (E)-7-[4-(4-fluorophenyl)-6-isopropyl-2-[methyl(methylsulfonyl)amino]pyrimidin-5-yl](3R,5S)-3,5-dihydroxyhept-6-enoic acid sodium salt.
