Reaktionsschritte
To a solution of (5-methyl-3-phenyl-isoxazol-4-yl)-methanol (220 mg, 1.16 mmol) in THF (2 mL) was added sodium hydride (55% dispersion in mineral oil, 996 mg, 22.8 mmol). After stirring for 0.5 h at ambient temperature 6-chloronicotinonitrile (161 mg, 1.16 mmol) was added and the reaction mixture was stirred for 5 h at ambient temperature. It was diluted with ethyl acetate (10 mL), washed with aqueous citric acid (10%, 10 mL), water (10 mL) and aqueous sodium chloride (saturated, 10 mL). The combined aqueous layers were extracted with ethyl acetate (10 mL). After drying over sodium sulfate and concentration purification by chromatography (SiO2, heptane:ethyl acetate=90:10 to 60:40) afforded the title compound (307 mg, 91%) as a white solid. MS: m/e=292.1 [M+H]+.
