실험 절차

A flask was charged with 3-(2-(trimethylsilyl)ethoxy)isonicotinonitrile (1.30 g, 5.90 mmol), THF (5 mL) and N,N-dibutyl-N-propylbutan-1-aminium fluoride (11.8 ml, 11.8 mmol) in THF was added. The reaction mixture was stirred at ambient temperature for 1 hour and then concentrated. The crude product was purified by silica gel chromatography, eluting with DCM and 5% methanol in DCM to give the desired product (0.7 g, 99% yield) as dark brown oil.
