Reaction Steps

A solution of 3.45 g (25 mmol) of sodium carbonate and 1.0 g (7.3 mmol) of anthranilic acid in 50 ml of water at 60° was treated with 2.09 g (10.95 mmol) of p-toluenesulfonyl chloride and held at 70° for 30 min. The reaction mixture was cooled to ambient temperature and acidified with 10% HCl. After standing for 18 hr the product was collected by filtration, washed with water and dried to give N-4-methylphenylsulfonylanthranilic acid as a solid, mp 226-229°.
