23 °C

A solution of 5-chloro-2-iodobenzoic acid (3.0 g, 10.62 mmol), SOCl2 (12 mL) and DMF (0.6 mL) was gently warmed with a heat gun until the mixture became homogeneous (15 min). The solution was maintained at 23° C. for additional 30 min and then the solution was concentrated. MeOH (24 mL) was added to the crude residue and the solution was maintained at 23° C. for 30 min. The solution was concentrated and the residue was purified by flash chromatography on Biotage silica gel cartridge (cyclohexane to cyclohexane:EtOAc=85:15) to afford methyl 5-chloro-2-iodobenzoate (3.02 g, 10.20 mmol, 96%).
