Oxone® (56.18 g, 91.4 mmol) was added to a solution of 2-chloro-3-cyano-4-(4-fluoro-2-methylphenyl)-6-(thiomorpholino)pyridine (26.54 g, 76.3 mmol) in 200 mL of NMP in a 1000-mL, 3-necked flask (equipped with a teflon paddle stirrer, septum with teflon-coated thermocouple, dry N2 adapter). The mixture was stirred at 25° C. for 20 hours, and diluted with 800 mL of water. The resulting mixture was stirred at 25° C. for 30 minutes. The precipitate was filtered, washed several times with H2O, and dried to afford 29.30 g (101.1%) of 2-chloro-3-cyano-4-(4-fluoro-2-methylphenyl)-6-(1,1-dioxo-thiomorpholin-4-yl)pyridine as a colorless solid.
