What are the common synthesis methods of 7-chloro-3-methyl-1-benzothiophene?

To prepare 7-bromo-3-methyl-1-heptene, it is often obtained by reacting allyl halide with a suitable Grignard reagent. The method is as follows:
First take allyl bromide, use anhydrous ether as a solvent, add magnesium chips, carefully initiate the reaction, and prepare allyl magnesium bromide Grignard reagent. This reaction needs to be carried out in an anhydrous and anaerobic environment, because Grignard reagent is easily decomposed in contact with water and oxygen.
Take another 1-bromo-5-methylhexane, also dissolved in anhydrous ether. The newly prepared Grignard reagent of allyl magnesium bromide is slowly dropped into the ether solution containing 1-bromo-5-methylhexane, and the reaction temperature is controlled to ensure the smooth progress of the reaction. In this nucleophilic substitution reaction, the allyl negative ion of allyl magnesium bromide is used as a nucleophilic reagent to attack the carbon attached to the bromine atom of 1-bromo-5-methylhexane, and the bromine ion leaves to form 7-bromo-3-methyl-1-heptene. After the reaction is completed, the reaction mixture is carefully treated with a dilute acid solution to quench the excess Grignard reagent and convert the generated organic magnesium salt into an organic compound. After that, the product is purified by conventional extraction, drying, distillation and other means. During extraction, a suitable organic solvent is selected to enrich the product in the organic phase. In the drying step, water is removed with a desiccant such as anhydrous magnesium sulfate. Finally, distillation is carried out, and the fraction is collected according to the boiling point of the product to obtain pure 7-bromo-3-methyl-1-heptene.
