Sulfuric Acid → 1-Methylethyl 2-mercaptobenzoate

Participants

Reaction Steps

Using a procedure similar to Example I, a mixture of 50.0 g (0.32 mole) of 2-mercaptobenzoic acid, 60 g (1.0 mole) of anhydrous isopropanol, 200 ml of benzene and 1.0 g of sulfuric acid (98%) was heated at reflux for 22 hours and yielded isopropyl 2-mercaptobenzoate: 13.2 g (20.1% of theory), bp 92°-93°C/0.7 mm.
