Reaction Steps

A solution of 2-methyl-1-propanol (0.56 mL, 6.06 mmol) in N,N-dimethylformamide (10 mL) was cooled to 0° C. and to this was added sodium hydride (242 mg, a 60% suspension in mineral oil, 6.06 mmol) in small portions. The turbid reaction mixture was stirred at 0° C. for 5 minutes and the temperature was raised to 23° C. Thereafter, the mixture was stirred at room temperature for 10 minutes and cooled again to 0° C. To the reaction mixture was added 2-fluoro-5-iodobenzonitrile (1.0 g, 4.04 mmol) and, after being warmed to room temperature, the reaction mixture was stirred for 1.5 hours. After the reaction was complete, water (20 mL) was added to the reaction mixture, which was extracted with ethyl acetate (3×30 mL). The organic phases were combined, washed with a saturated aqueous sodium chloride solution (3×30 mL), and thereafter dried over anhydrous magnesium sulfate. After removing magnesium sulfate by filtration, the solvent was concentrated under reduced pressure. The crude product obtained was purified by silica gel chromatography (hexane/ethyl acetate=98/2) to obtain the title compound (950 mg). Yield, 78%.
