Reaction Steps

238 mg (7.9 mmol) of sodium hydride (80% in oil) and 20 ml of DMF were introduced into a three-necked flask, a solution of 2 g (7.2 mmol) of methyl 2-hydroxy-4-iodobenzoate in 50 ml of DMF was added dropwise and stirring was carried out until gas evolution had ceased. 540 μl (8.6 mmol) of iodomethane were then added and stirring was carried out at room temperature for two hours. The reaction mixture was poured into water and extracted with ethyl ether. The organic phase was separated by settling, dried over magnesium sulfate and evaporated. 2.1 g (100%) of methyl 4-iodo-2-methoxybenzoate were recovered.
