Hydrogen Bromide → HCID 12111378, compound

Participants

Reaction Steps

In 40 mL of propyl acetate, was dissolved 2.26 g (11.7 mmol) of the compound obtained in Example 13. The refluxing was carried out for 30 minutes. The solution was then cooled, and 1.59 mL (14 mmol) of a 48% hydrobromic acid was added. The resulting mixture was allowed to stand at room temperature for 30 minutes. Ethyl acetate was subsequently added, and the obtained mixture was washed with water, dried with magnesium sulfate and vacuum concentrated to obtain 2.49 g of 3-(bromomethyl)-4,6-dimethylbenzo[b]thiophene. The yield was 84%.
