25542-62-5, A common compound: 25542-62-5, name is Ethyl 6-bromohexanoate, belongs to esters-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
Example 9 Synthesis of 3-[3-(5-carboxypentyl)-5-iodo-2,3-dimethyl-3H-1-indoliumyl]-1-propanesulfonate (2) A mixture of 13.4 g (0.12 mol) of potassium tert-butoxide and 100 g of tert-butanol was stirred and heated until the tert-butoxide totally dissolved. The solution was cooled to about 50 C. and 17 g (0.12 mmol) of ethyl 2-methylacetoacetate was added dropwise. Ethyl-6-bromohexanoate (30 g, 0.13 mmol) was then added dropwise and the reaction mixture was stirred and refluxed for 5 hours. The mixture was filtered and the solvent was removed under reduced pressure. The residue was partitioned between 1M HCl and chloroform. The organic layer was dried over magnesium sulfate and purified on silica gel using 1:10 ethyl acetate/hexane as the eluent to yield 25 g (75%) of diethyl 2-acetyl-2-methyloctanedioate (3) as yellow liquid.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Ethyl 6-bromohexanoate, other downstream synthetic routes, hurry up and to see.
