Methanol → Methyl 4-Iodo-3-methylbenzoate

Participants

Reaction Steps

24.4 g (0.093 mol) of 3-methyl-4-iodobenzoic acid and 250 ml of methanol were introduced into a round-bottomed flask and 2.5 ml of concentrated sulfuric acid were added dropwise. The mixture was heated at reflux for 12 hours, the reaction medium evaporated, taken up in ethyl acetate and water, the organic phase decanted off, dried over magnesium sulfate and evaporated. The residue was triturated in methanol, filtered and 21.9 g (85%) of the expected methyl ester of melting point 58-9° C. were recovered.
