Methanol → HCID 54190766, compound

Participants

Reaction Steps

A solution of potassium peroxymonosulphate (23.8 g) in water was added to a solution of 4-methyl-2-(methylsulphenyl)benzoic acid (4.7 g) in methanol. The mixture was stirred for 5 hours and left to stand overnight at room temperature. The methanol was removed by evaporation and the resulting suspension was diluted with water and extracted with chloroform. The organic layer was dried (anhydrous magnesium sulphate) and filtered. The filtrate was evaporated to dryness and the residue was triturated with a mixture of ether and cyclohexane to give 4-methyl-2-(methylsulphonyl)benzoic acid (4.4 g) as a cream solid, m.p. 174°-174.5° C.
