실험 절차

A solution of 4.23 g (10.67 mmol) of 3-(2,6-difluoro-3,5-dimethoxy-phenyl)-1-ethyl-7-methylsulfanyl-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one in 90 mL of chloroform was treated with 3.35 g (12.80 mmol) of 3-phenyl-2-(phenylsulfonyl)-oxaziridine and stirred at room temp. under N2 atmosphere overnight. Crude product was purified by medium-pressure chromatography eluting with straight ethyl acetate and a gradient of 1% to 3% MeOH in chloroform to give 4.45 g (quantitative) title compound. MS (APCI) (m+1)/z 413.1.
