hello

first make dehydrohalogenation to 1-bromopropane  by using C2H5ONa & EtOH at 55 C0 as follow:

CH3CH(Br)CH3 CH2=CHCH3

then use anti markanikove rule by adding the HBr in presence of H2O2 to give 1-bromopropane

3 steps:
elimnation to the propene (ex. KOtBu)
Hydroboration (BH3, NaOOH)
Bromination (PBr3)
cheers
