Yield: 100%
Reaction Conditions:
with dmap;sodium carbonate in toluene for 1 h;Cooling with ice;
Steps:
122.1 (1) Production of 5-bromopentyl acetate
To a reaction flask, 33.4 g (200 mmol) of 5-bromo-1-pentanol, 25.4 g (240 mmol) of anhydrous sodium carbonate, 2.4 g (20 mmol) of N,N-dimethyl-4-aminopyridine and 200 mL of toluene were added. While the mixture was stirred under ice cooling, 22.5 g (220 mmol) of acetic anhydride was added dropwise thereto. After the completion of the dropwise addition, the mixture was stirred for 1 hour under ice cooling. The resultant reaction mixture was washed successively with water twice, with dilute hydrochloric acid and then with water. The toluene was distilled off under reduced pressure to obtain 41.8 g of 5-bromopentyl acetate. Yield: quantitative.
