Reaction Steps

905 μl (2 eq) of methyl iodide and 2.1 g (1.05 eq) of silver carbonate are added successively to a solution of 2.12 g (7.26 mmol) of 6-hydroxy-5-iodo-2-(methylthio)nicotinonitrile in 20 ml of 1,4-dioxane. The reaction medium is stirred at 60° C. for 5 hours. The solid is filtered and the residue rinsed thoroughly with methanol. The filtrate is evaporated and the residue purified by silica column chromatography (4:6 dichloromethane/cyclohexane as eluent) to yield 1.52 g (68%) of 5-iodo-6-methoxy-2-(methylthio)nicotinonitrile in the form of a white powder.
