Procedure
To a stirred suspension of 350 mg (1.22 mmol) 5-bromo-4-furan-2-yl-6-methylsulfanyl-pyrimidin-2-ylamine in 30 ml dichloromethane was added 1.28 g (4.89 mmol) 3-phenyl-2-(phenylsulfonyl)oxaziridine and stirring continued for 16 hours at room temperature. The reaction mixture was then concentrated in vacuo and the residue recrystallised from hexane/dichloromethane to afford 225 mg (61%) 5-bromo-4-furan-2-yl-6-methanesulfinyl-pyrimidin-2-ylamine as a beige crystalline solid. EI-MS m/e (%): 303 (M{flBr}+, 24), 301 (M{79Br}+24), 257(48), 255 (50), 198 (81), 196(84), 117(100).
