실험 절차

1.42 g (1.1 eq) of 70% 3-chloroperbenzoic acid is added to a solution of 1.6 g (5.23 mmol) of 5-iodo-6-methoxy-2-(methylthio)nicotinonitrile in 20 ml of dichloromethane. The reaction medium is stirred at room temperature for 1 hour. Ethyl acetate is added and the organic phase is washed with saturated sodium bicarbonate solution, dried on magnesium sulfate, filtered and evaporated to yield 1.63 g (97%) of 5-iodo-6-methoxy-2-(methylsulfinyl)nicotinonitrile in the form of a white powder which may also contain 5-iodo-6-methoxy-2-(methylsulfonyl)nicotinonitrile in small proportions (<20%). If necessary, the mixture is used as-is in the following steps.
