Versuchsvorschrift

E-6-{2-[2-(N-methyl-N-methanesulfonylamino)-4-(4-fluorophenyl)-6-isopropyl-pyrimidin-5-yl]vinyl}-(4R,6S)-4-hydroxy-3,4,5,6-tetrahydro-2H-pyran-2-one (4.0 g), water (20.0 mL), and calcium hydroxide (0.64 g) was added to a reactor. The reaction mixture was stirred at room temperature for 3 hours and then filtered under reduced pressure. The resulting white solid was dried to obtain E-7-[2-(N-methyl-N-methanesulfonylamino)-4-(4-fluorophenyl)-6-isopropyl-pyrimidin-5-yl]-(3R,5S)-3,5-dihydroxyhept-6-enoic acid 1/2 calcium salt (4.1 g, yield 95%).
