To a stirred suspension of 2.00 g (9.97 mmol) 2-amino-4-chloro-6-methylsulfanyl-pyrimidine-5-carbonitrile in 6 ml dichloromethane and 20 ml DMF was added 5.21 g (19.9 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 ether/dichloromethane to afford 1.50 g (69%) 2-amino-4-chloro-6-methanesulfinyl-pyrimidine-5-carbonitrile as a white crystalline solid. ES-MS m/e (%): 239 (M+Na+, 45), 234 (M+NH4+, 55), 217 (M+H+, 100).
