Reaction Steps
2-(2,6-dichloro-4-trifluoromethylphenyl)-2H-1,2,3-triazole-4-carboxaldehyde (1 g) was oxidised using chromium trioxide (26.67 g) in water (40 ml) and concentrated sulphuric acid (23 ml), made up to 100 ml. The product was extracted with ether and worked up in conventional manner to give 2-(2,6-dichloro-4-trifluoromethylphenyl)-2H-1,2,3-triazole-4-carboxylic acid, m.p. 155°-157°.
