実験手順

To a solution of (5-phenylisoxazol-3-yl)methyl methanesulfonate (example 33d) (261 mg, 1.03 mmol) in anhydrous DMSO (8 mL) was added NaCN (252 mg, 5.15 mmol). The reaction mixture was heated at 80° C. under N2 for 15 hours, then diluted with EtOAc and washed with H2O (5×). The combined organic layers were dried over MgSO4, filtered and concentrated to yield a yellow solid (209 mg, 40%). 1H NMR (DMSO-d6, 400 MHz): 4.30 (s, 2H), 7.12 (s, 1H), 7.55-7.57 (m, 3H), 7.89-7.92 (m, 2H).
