Carbon tetrabromide → HCID 86620175, compound

Participants

Reaction Steps

A solution of tetrabromomethane (2.1 g, 6.6 mmol) in dry methylene chloride (20 mL) was added dropwise to an ice-cooled solution of 3-(4-bromophenyl)-3-iodoprop-2-en-1-ol (1.5 g, 4.4 mmol) and triphenylphosphine (2.4 g, 9.0 mmol) in dry methylene chloride (50 mL). The reaction mixture was stirred at room temperature for 2 h and the solvent was evaporated in vacuo. Under nitrogen atmosphere, N,N-diisopropylethylamine (1.2 g, 9.0 mmol) and ethyl (4-mercapto-2-methylphenoxy)acetate (1.5 g, 6.6 mmol; Bioorg. Med. Chem. Lett. 2003, 13, 1517) were added to the residue. The reaction mixture was stirred for 3 h, filtered through a short path of silica gel and the filtrate was evaporated in vacuo. The residue was purified by column chromatography (silica gel Merck 60, hexane/ethyl acetate 1:0–9:1) giving 0.80 g of the ester. Yield: 0.80 g (40%).
