Hydrogen Bromide → 2-(4-Bromophenethyl)-benzyl bromide

Participants

Reaction Steps

A suspension of 28.5 g. (0.098 mole) of 2-(4-bromophenethyl)-benzyl alcohol in 150 ml. of 48% hydrobromic acid is stirred at reflux for 3 hours. The cooled two-phase mixture is extracted with benzene. Evaporation of the washed and dried benzene extract under reduced pressure leaves the product as the residual solid, m.p. 63°-75° C. Recrystallization from hexane affords purified material, m.p. 76°-77.5° C. A sample for analysis melts at 76.5°-78° C. after further recrystallization from hexane.
