E-6-{2-[2-cyclopropyl-4-(4-fluorophenyl)quinolin-3-yl]vinyl}-(4R,6S)-4-hydroxy-3,4,5,6-tetrahydro-2H-pyran-2-one (2.0 g), water (20.0 mL), and calcium hydroxide (0.4 g) were 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 (3R,5S,6E)-7-[2-cyclopropyl-4-(4-fluorophenyl)quinolin-3-yl]-3,5-dihydroxy hept-6-enoic acid 1/2 calcium salt (2.0 g, yield 91%).
