With carbon tetrabromide; triphenylphosphine; In dichloromethane; at 0 - 20℃; | [00202] A solution of 3-chloro-4-fluorobenzaldehyde (3 g) in THF (40 ml) was added over 2 minutes to a stirred suspension of sodium borohydride (1.07 g) in methanol (40 ml) at 0 C. The mixture was allowed to warm to room temperature and then quenched with water. The resulting suspension was partitioned between water and diethyl ether and the combined organic extracts were dried and concentrated in vacuo. The residue was dissolved in dichloromethane (90 ml) and triphenylphosphine (4.62 g) and tetrabromomethane (6.64 g) were added at 0 C. The mixture was allowed to warm to room temperature overnight then concentrated in vacuo and the residue purified by column chromatography using iso-hexane as eluent to yield the desired product (3.57 g, 85%). NMR: delta 4.7 (s, 2H), 7.4 (m, 2H), 7.7 (m, 1H). | |
With carbon tetrabromide; triphenylphosphine; In dichloromethane; for 3h; | Intermediate 50 (1.25 mmol), triphenylphosphine (1.87 mmol) and carbon tetrabromide (1.87 mmol) were stirred in anhydrous DCM, under nitrogen for 3 hours. The solvent was removed under reduced pressure and the crude material was purified by chromatography on silica gel to give intermediate 51, which was a colourless oil. Intermediate 51 was characterized by the following spectroscopic data: 1H NMR (DMSO-d6, 400 MHz) (ppm) 4.43 (s, 2H), 7.13 (t, J=8.37 Hz, 1H), 7.26-7.28 (m, 1H), 7.44-7.47 (d, J=6.70 Hz, 1H). | |
With phosphorus tribromide; In dichloromethane; at 0 - 20℃; for 1h;Inert atmosphere; | To a solution of (3-chloro-4-fluoro-phenyl)-methanol (4.3 g, 26.8 mmol) in DCM (20 mL) was added PBr3 (1 mL) at 0 C. The resulting mixture was stirred at room temperature for 1 hour before it was quenched with satd. aq. NaHC03 solution. The organic solution was washed with water, brine, dried over anhy. Na2S04 and concentrated in vacuo to give the desired product (3.7 g, 61.9%). It was used directly in the next step, without further purification |
