Carbon tetrabromide → 1-(2-Bromoethyl)-2-chloro-4-nitrobenzene

Participants

Reaction Steps

To a stirred solution of 2-chloro-4-nitrophenethyl alcohol (1.17 g) in dichloromethane (15 ml) were added carbon tetrabromide (2.12 g) and triphenylphosphine (1.67 g) at room temperature, and the mixture was stirred for 15 minutes. The solvent was removed in vacuo, and purification of the residue by flash column chromatography on silica gel (eluent: hexane/ethyl acetate=9/1) gave 1-(2-bromo-ethyl)-2-chloro-4-nitrobenzene (1.30 g).
