Reaction Conditions

Reaction Steps

To a solution of 5-bromo-[1,1′-biphenyl]-2-carboxylic acid (5 g, 18.2 mmol) in MeOH (30 mL) was added SOCl2 (10 mL) dropwise. The reaction mixture was heated to 70° C. for 2 h, then cooled to RT. The mixture was concentrated, adjusted to pH=7-8 with saturated aqueous NaHCO3 and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo and purified by normal phase silica gel column (EtOAc/PE 50:1) to afford methyl 5-bromo-[1,1′-biphenyl]-2-carboxylate as a colorless oil.
