(3-chloro-2-fluorophenyl)methanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of (3-chloro-2-fluoro-phenyl)-methanol (3.2 g, 20 mmol) in DCM (20 mL) was added dropwise PBr3 (1 mL) at 0° C. The reaction mixture was stirred at room temperature for another 1 hour before quenching with satd. aq. NaHCO3 solution. The organic layer was washed with brine, dried over anhy. Na2SO4, filtered and concentrated in vacuo to give the desired product without further purification (4.1 g, 92%). MS: 223.2 (M+H)+. before quenching with satd The organic layer was washed with brine dried over anhy Na2SO4, filtered concentrated in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2-fluoro-3-chloro-benzaldehyde (4.74 g, 30 mmol) in THF (20 mL) was added NaBH4 (1.48 g, 40 mmol). The resulting mixture was stirred at room temperature for 30 min before diluting with DCM. The organic layer was washed with water and brine. The combined organic layers were dried over anhy. Na2SO4, filtered and concentrated in vacuo to give desired product without further purification (4.8 g, 100%). MS: 161.0 (M+H)+. The organic layer was washed with water and brine The combined organic layers were dried over anhy Na2SO4, filtered concentrated in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
