2-(Benzenesulfonyl)-3-phenyloxaziridine → 5-Ethyl-4-furan-2-yl-6-methanesulfinyl-pyrimidin-2-ylamine

Participants

Reaction Steps

To a stirred suspension of 350 mg (1.49 mmol) 5-ethyl-4-furan-2-yl-6-methylsulfanyl-pyrimidin-2-ylamine in 15 ml dichloromethane was added 780 mg (3.00 mmol) 3-phenyl-2-(phenylsulfonyl)oxaziridine and stirring continued for 16 hours at room temperature. The reaction mixture was then partitioned between dichloromethane and water and the phases separated. The organic phase was dried over sodium sulfate and concentrated in vacuo. Chromatography (ethyl acetate then methanol/ethyl acetate 1/5) afforded 170 mg (46%) 5-ethyl-4-furan-2-yl-6-methanesulfinyl-pyrimidin-2-ylamine as a yellow crystalline solid. ES-MS m/e (%): 252 (M+H+, 100).
