Reaction Steps

To a mixture of 3-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]propan-1-ol (2.6 g) and benzene (50 ml) was added phosphorus tribromide (PBr3) (2.1 g), which was stirred for 2 hours at 70° C. The reaction mixture was poured into water, which was subjected to extraction with ethyl acetate. The ethyl acetate layer was washed with water and dried (MgSO4), then the solvent was distilled off to leave 3-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]propyl bromide (0.98 g, 32%), which was recrystallized from ethyl acetate--hexane to give colorless needles, m.p.78°-79° C.
