实验步骤: To a stirred solution of 2-fluoro-3-methylbenzonitrile (200 mg, 1.5 mmol) in 1,2-dichloroethane (30 ml) was added NBS (266 mg, 1.49 mmol) and AIBN (29 mg, 0.15 mmol) at RT. The reaction mixture was then heated to 80° C., and the reaction mixture was stirred for 2 h. After complete consumption of the starting material (by TLC), the reaction mixture was cooled to RT. The volatiles were removed under reduced pressure to obtain the crude material. Purification by silica gel column chromatography eluting with 2-3% EtOAc/hexane afforded compound I-6 (250 mg, 1.15 mmol, 78%) as colorless liquid. 1H NMR (500 MHz, CDCl3): δ 7.69-7.65 (m, 1H), 7.62-7.58 (m, 1H), 7.28-7.25 (m, 1H), 4.50 (s, 2H). After complete consumption of the starting material (by TLC) the reaction mixture was cooled to RT The volatiles were removed under reduced pressure

实验步骤: 3-(Bromomethyl)-2-fluorobenzonitrile (Intermediate 84, 1.39 g, 6.49 mmol) was dissolved in MeOH (10 mL) and sodium methoxide (1.238 mL, 6.49 mmol) was added. The mixture was stirred at r.t. for 2 h. This mixture was concentrated and then partitioned between water and EtOAc. The organic layer was separated and then concentrated in vacuo. The resulting residue was purified by flash chromatography using EtOAc/heptanes as eluent to give the title compound (0.900 g, 84% yield): 1H NMR (500 MHz, DMSO-d6) δ ppm 3.32 (s, 3 H) 4.52 (br. s, 2 H) 7.42 (t, 1 H) 7.77-7.84 (m, 1 H) 7.86-7.92 (m, 1 H); MS (EI) m/z 166 M+.

实验步骤: NBS (1.729 g, 9.71 mmol) was added to a solution of 2-fluoro-3-methylbenzonitrile (1.25 g, 9.25 mmol) in acetonitrile (25 mL). The obtained mixture was refluxed, and then benzoic peroxyanhydride (0.045 g, 0.18 mmol) was added. The reaction mixture was refluxed overnight, then cooled to r.t. and water was added. The aqueous phase was discarded and the organic phase was dried over MgSO4 and concentrated. The crude product was purified by flash chromatography using a gradient of EtOAc in heptane as eluent to give the title compound (1.39 g, 70% yield): 1H NMR (500 MHz, DMSO-d6) δ ppm 4.75 (s, 2 H) 7.43 (t, 1 H) 7.93 (t, 2 H); MS (EI) m/z 213 M+.
