Reaction Steps
41 g of 2,5-dichloro-4-methylbenzoic acid are added in portions to a mixture of 100 ml of concentrated H2SO4 and 20 ml of 68% strength HNO3. The mixture is kept at 50° for 3 hours and then poured onto 600 g of ice. The solid which has precipitated is isolated, dried and stirred with a little toluene. Melting point: 210°-18°, yield: 43.8 g.
