The mixture was heated at 75° C. overnight. After cooling to room temperature, the mixture was diluted with ether and washed with water and brine. The solution was dried over Na2SO4 and concentrated under reduced pressure. The product was dried in a vacuum oven at 40° C. for 2 h to give 1-azido-3-(3-bromophenyl)propan-2-ol as a yellow oil which was used without purification. Yield (8.6 g, 98% crude).
