Hydrochloric Acid → 4-Chloro-3-mercapto-2-methylbenzoic acid

Participants

Reaction Steps

6.61 g (purity 85% by weight, 100.1 mmol) of KOH were added to 4.80 g (16.7 mmol) of methyl 4-chloro-3-(dimethylaminocarbonylthio)-2-methylbenzoate in 150 ml of methanol, and the mixture was stirred under reflux for two days. The reaction mixture was freed from solvent, water was added to the residue, which was then acidified with 1M HCl, and the solid was collected by filtration. This gave 3.2 g of pure product.
