Reaction Steps
To a suspension of sodium hydride (136 mg, 5.39 mmol) in N,N-dimethylformamide (5 mL) was added a solution of 2-(isoxazol-3-yl)acetonitrile (233 mg, 2.16 mmol) in N,N-dimethylformamide (2.5 mL) at 0° C. After the addition, the mixture was warmed to room temperature and stirred for 1 h. The mixture was cooled to 0° C. and 1,2-dibromoethane (0.3 mL, 3.48 mmol) was added. The reaction mixture was stirred at 0° C. for 4 h. Water was added to the mixture. The mixture was extracted with ethyl acetate (3×). The combined organics were washed with water, washed with aqueous hydrochloric acid (1N), washed with aqueous sodium bicarbonate and brine. The organics were dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was dissolved with dichloromethane and washed with aqueous lithium chloride solution (10%). The organics were dried over sodium sulfate, filtered and concentrated under reduced pressure and dried under a stream of nitrogen to afford 1-(isoxazol-3-yl)cyclopropanecarbonitrile (243 mg). 1H NMR (500 MHz, CDCl3) δ 1.71-1.76 (m, 2H), 1.79-1.83 (m, 2H), 6.51 (s, 1H), 8.40 (s, 1H). The material was used without further purification.
