The synthetic route is as follows.
To a solution of the above crude 3-(bromomethyl)benzo[d]isoxazole (15.3 g) in CH3CN (100 mL) was added a solution of KCN (4 g, 61 mmol) in water (19 mL). The resulting solution was stirred overnight at 40C, and then quenched with water (200 mL) and extracted with ethyl acetate (4 x 200 mL). The combined organic layers were washed with brine (2 x 100 mL), dried over anhydrous sodium sulfate and concentrated in vacuo to afford a residue, which was purified by a silica gelcolumn chromatography eluting with 1 % – 2% ethyl acetate in petroleum ether to afford 2-(benzo[d]isoxazol-3-yl)acetonitrile as a yellow solid (1.15 g, 15 ). LC/MS (ES, m/z): [M+H]+ 159.0 *H NMR (300 MHz, DMSO) delta 7.87 – 7.84 (d, / = 8.10 Hz, 1H), 7.66 – 7.61 (m, 2H), 7.47 – 7.40 (m, 1H), 4.13 (s, 2H)
