Methanol → Methyl 4-(methylsulfonyl)benzoate

Participants

Reaction Steps

250 ml of a desiccated methanol solution containing 50 g (0.25 mol) of p-methylsulfonylbenzoic acid and 10 ml of concentrated sulfuric acid was refluxed by heating for 8 hours. The reaction mixture was then cooled with ice and the crystals thus precipitated were collected by filtration and washed with methanol to obtain 48.2 g (0.225 mol) of the above described compound.
