General procedure for the synthesis of 5-bromo-1-pentanol from 1,5-pentanediol: 1,5-pentanediol (14 g, 0.135 mol), 40% hydrobromic acid (28 mL, 0.2 mol), and 60 mL of benzene were added to a 250 mL three-necked flask, and reacted for 15 h in an oil bath at 70-80 °C. The reaction progress was monitored by TLC until the raw material spots disappeared. After completion of the reaction, the reaction mixture was washed sequentially with 5% sodium hydroxide solution, 10% hydrochloric acid and saturated saline, and then dried with anhydrous sodium sulfate. The crude product was purified by silica gel column chromatography (eluent: petroleum ether/ethyl acetate, V/V = 8:1) and concentrated to give 5-bromo-1-pentanol (20.1 g, 89.1% yield) as colorless to light yellow liquid. | [References]
