3,3''-DIBROMO-4,4''-DIMETHOXYBIPHENYL synthesis

3synthesis methods
-

Yield: 90%

Reaction Conditions:

with N-Bromosuccinimide in acetonitrile for 5 h;Reflux;

Steps:

A representative synthetic procedure of compounds 7 and 8 is as follows
NBS (for 7, 428 mg, 2.4 mmol; for 8, 783 mg, 4.4 mmol) was added to a solution of compound 2 (430 mg, 2.0 mmol) in MeCN (10 mL) at rt. The reaction mixture was stirred at reflux for 5 h. The reaction mixture was concentrated to yield the residue. The residue was extracted with EtOAc (3×30 mL). The combined organic layers were washed with brine, dried, filtered, and evaporated to afford crude product. Purification on silica gel (hexanes/EtOAc=10/1-6/1) afforded compound 7 or 8.
