with hydrogen bromide in toluene; for 7.5 h;Reflux;Time;
Steps:
2.2.1; 2.2.2 Synthesis of compound 2
Dissolve 1,9-nonanediol (40g, 0.25mol) in 350mL anhydrous toluene, and add 40% hydrobromic acid (60.68g, 0.3mol) to the solution, and heat and reflux for 7.5 hours. Cooled to room temperature, quenched with saturated sodium bicarbonate, extracted, combined the organic phases, washed with saturated brine three times, dried over anhydrous magnesium sulfate and concentrated. The crude product was purified by column chromatography to obtain 52.7g of pure product The yield is 95%.
