20.1 g (0.16 mol) of DMAP were added to 297.4 g (1.64 mol) of 6-bromo-1-hexanol in 1500 ml of THF. A solution of 184.4 g (1.81 mol) of acetic anhydride in 300 ml of THF was added dropwise in such a way that the reaction temperature did not exceed 30° C. After completion of the addition, the mixture was stirred for a further 30 minutes. The reaction mixture was mixed with 500 ml of diisopropyl ether and extracted successively with 700 ml each of water, 2× saturated NaHCO3 solution and water. After drying over sodium sulfate, the solvent was removed in vacuo. 352.8 g (1.58 mol, 96%) of 6-bromohexyl acetate were obtained.
