Methanol → Methyl 2-chloro-5-iodobenzoate

Participants

Reaction Steps

A solution of 2-chloro-5-iodo-benzoic acid (25.63 g, 90 mmol) in methanol (500 mL) saturated with HCL gas was stirred at room temperature for 48 h. The reaction mixture was concentrated in vacuo, diluted with 1:1 ethyl acetate/Diethyl ether and washed with saturated aqueous sodium bicarbonate and brine. The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo to afford the title compound (25.0 g).
