2-(3-bromopropyl)-1,3-difluorobenzene

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

Procedure: 6.86 g (39.8 mmol) of 3-(2,6-difluorophenyl)propan-1-ol (Example 1.2.4) is dissolved in 50 ml toluene and 19.1 g (92.0 mmol) of thionyl bromide is added. The mixture is refluxed for 3 hours, the solvent is eliminated and excess thionyl bromide is eliminated. Then the residue is purified by flash chromatography (cyclohexane). Yield: 6.98 g. The mixture is refluxed for 3 hours Then the residue is purified by flash chromatography (cyclohexane)
