Procedure

HBr gas (39.4 g, 486 mmol) was bubbled into a solution of 2-vinylnaphthalene (75 g, 486 mmol) in benzene (100 mL) over a period of 7-8 hours at 55-60° C. The solution was cooled to room temperature, and the benzene with the small excess of HBr was removed under vacuum yielding 105 g (91%) crude of 2-(1-Bromoethyl)-naphthalene. It was used without further purification. C12H11Br; MS: 235.12.
