OsO4/NaIo4 Oxidation of Quinine (1). In a 100-mL round-bottom flask 0.753 g of quinine (2.32 mmol) was added to 40 mL of 80% acetic acid with stirring. After cooling to 0" C, 1.483 g of NaI04 (6.93 mmol) was added followed by a few crystals of OsOb The solution became opaque purple as it was stirred for 5 h on ice.
