Reaction Steps

3.05 mL (5.04 mmol) of potassium 2-methylpropan-2-olate and then 286 μL (1.8 eq) of iodomethane are added dropwise under nitrogen to a solution of 700 mg (2.52 mmol) of 6-(2,4-difluorophenylamino)-2-(methylthio)nicotinonitrile in 20 mL of N,N-dimethyl formamide. The reaction medium is stirred at room temperature for 24 hours and then 126 μL (0.8 eq, 2.02 mmol) of iodomethane is added. The reaction medium is stirred at room temperature for 2 additional hours. Water is added and the product is extracted with ethyl acetate. The organic phase is dried on anhydrous magnesium sulfate, filtered, and evaporated to yield 660 mg (90%) of 6-((2,4-difluorophenyl)(methyl)amino)-2-(methylthio)nicotinonitrile in the form of a brown solid.
