実験手順
To a stirring solution of 4-(isopropylamino)-2-(methylthio)pyrimidine-5-carboxamide (170 g, 0.751 mol) in chloroform (22 L) was added portion-wise 3-phenyl-2-(phenylsulfonyl)-1,2-oxaziridine (235.6 g, 0.902 mol) and the resulting solution was stirred at ambient temperature overnight. An additional amount of 3-phenyl-2-(phenylsulfonyl)-1,2-oxaziridine (19.6 g, 0.075 mol) was added and the mixture was then stirred overnight at ambient temperature. The reaction solution was concentrated under reduced pressure to give the crude product as a white solid. The solids were triturated with ethyl acetate (1.5 L) at ambient temperature for 1 h, filtered, washed with ethyl acetate (250 mL), and dried in a vacuum oven overnight at 45° C. to afford 4-(isopropylamino)-2-(methylsulfinyl)pyrimidine-5-carboxamide (167.7 g, 92% yield) as white solid. MS (ESI) m/z 243.2 [M+1]+.
