HCID 866126904-(2-Bromoethyl)-naphthalenesulfonyl chloride

Procedure

1-(2-bromoethyl)naphthalene and sulfonyl chloride can be allowed to react with each other to yield 4-(2-bromoethyl)-naphthalenesulfonyl chloride. Next, 4-(2-bromoethyl)-naphthalenesulfonyl chloride is esterified with methyl alcohol, and is then subjected to dehydrobromination, whereby methyl 4-ethenyl-1-naphthalenesulfonate as a target can be obtained.
