Tetra-n-butylammonium tribromide → HCID 58764135, compound

Participants

Reaction Steps

A solution of tetrabutyl ammonium tribromide (9.9 g, 20.5 mmol) in CHCl3 (60 mL) was added to a stirred solution of 5-ethoxy-2-ethyl-phenol (3.1 g, 18.6 mmol) dissolved in CHCl3 (90 mL). The reaction mixture was stirred for 30 mins and then quenched with 5% solution of sodium thiosulfate (30 mL). The biphasic mixture was stirred for 30 mins and then the layers were separated. The organic layer was washed with 1 N HCl, brine, dried over Na2SO4 and concentrated to a red oil. Purification by flash column chromatography (0% to 15% EtOAc in hexanes) gave the product as an oil (2.6 g, 58%).
