2-(Benzenesulfonyl)-3-phenyloxaziridine → HCID 18507414, compound

Participants

Reaction Steps

To a stirred suspension of 2.65 g (10.7 mmol) 2-amino-4-(methylthio)-6-(2-thienyl)-pyrimidine-5-carbonitrile in 200 ml dichloromethane was added 2.79 g (10.7 mmol) 3-phenyl-2-(phenylsulfonyl)oxaziridine and stirring continued for 16 hours at room temperature. The resulting crystals were collected by filtration and washed with 30 ml dichloromethane to afford 1.54 g (55%) 2-amino-4-methanesulfinyl-6-thiophen-2-yl-pyrimidine-5-carbonitrile as a white crystalline solid. EI-MS m/e (%): 264 (M+, 20), 218 (32), 201 (20), 159 (100).
