2-{[5-Fluoro-2-({3-[2-(4-morpholinyl)ethyl]phenyl}amino)-4-pyrimidinyl]amino}-N-[2-(methylthio)ethyl]benzamide (100 mg, 0.20 mmoles) was dissolved in 5 mL of THF and 5 mL of methanol, and treated with a solution of OXONE® reagent (a registered trademark of DuPont, 15 equivalents) in 5 mL water. The system was stirred for 48 h at room temperature, and then filtered and concentrated to dryness. The residue was immobilized onto silica gel and purified by silica gel chromatography, using a gradient of 100% A to 90% A-10% B, where “A” is chloroform and “B” is 10:90:1 methanol-chloroform-concentrated aqueous ammonium hydroxide). The title compounds 2-{[5-fluoro-2-({3-[2-(4-morpholinyl)ethyl]phenyl}amino)-4-pyrimidinyl]amino}-N-[2-(methylsulfinyl)ethyl]benzamide (Example 187) and 2-{[5-fluoro-2-({3-[2-(4-morpholinyl)ethyl]phenyl}amino)-4-pyrimidinyl]amino}-N-[2-(methylsulfonyl)ethyl]benzamide were isolated and characterized.
