실험 절차

E-(6-{2-[2-(N-methyl-N-methanesulfonylamino)-4-(4-fluorophenyl)-6-isopropyl-pyrimidin-5-yl]vinyl}-[(4R,6S)-2,2-dimethyl-[1,3]dioxan-4-yl])-N-methoxy-N-methyl-acetamide (4.0 g), acetonitrile (25.0 mL), and nitric acid (0.49 mL) were added to a reactor and then the reaction mixture was stirred at 50˜60° C. for 3 hours. The reaction mixture was concentrated under reduced pressure and then ethyl acetate (25.0 mL) and water (25.0 mL) were added thereto. The separated organic layer was dried under reduced pressure to obtain 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 (1.9 g, yield 58%).
