实验步骤: BBr3 (16.6 g, 66 mmol) was slowly added to a solution of 2-(4-chloro-3-methoxyphenyl)acetonitrile (12 g, 66 mmol) in DCM (120 mL) at −78° C. under N2. The reaction temperature was slowly increased to room temperature. The reaction mixture was stirred overnight and then poured into ice and water. The organic layer was separated, and the aqueous layer was extracted with DCM (40 mL×3). The combined organic layers were washed with water, brine, dried over Na2SO4, and concentrated under vacuum to give (4-chloro-3-hydroxy-phenyl)-acetonitrile (9.3 g, 85%). 1H NMR (300 MHz, CDCl3) δ 7.34 (d, J=8.4 Hz, 1H), 7.02 (d, J=2.1 Hz, 1H), 6.87 (dd, J=2.1, 8.4 Hz, 1H), 5.15 (brs, 1H), 3.72 (s, 2H). The organic layer was separated the aqueous layer was extracted with DCM (40 mL×3) The combined organic layers were washed with water, brine dried over Na2SO4 concentrated under vacuum

实验步骤: To a solution of 4-bromomethyl-1-chloro-2-methoxy-benzene (68.5 g, 0.29 mol) in C2H5OH (90%, 500 mL) was added NaCN (28.5 g, 0.58 mol). The mixture was stirred at 60° C. overnight. Ethanol was evaporated and the residue was dissolved in H2O. The mixture was extracted with ethyl acetate (300 mL×3). The combined organic layers were washed with brine, dried over Na2SO4 and purified by column chromatography on silica gel (Petroleum Ether/EtOAc 30:1) to give 2-(4-chloro-3-methoxyphenyl)acetonitrile (25 g, 48%). 1H NMR (400 MHz, CDCl3) δ 7.36 (d, J=8 Hz, 1H), 6.88-6.84 (m, 2H), 3.92 (s, 3H), 3.74 (s, 2H). 13C NMR (100 MHz, CDCl3) δ 155.4, 130.8, 129.7, 122.4, 120.7, 117.5, 111.5, 56.2, 23.5.
