Nitric Acid → HCID 67405888, compound

Participants

Reaction Steps

To 8.7 g of N-(2, 6-diisopropylphenyl)-p-toluenesulfonamide (8.7 g) were added 6.3 ml of 60% nitric acid, 50 ml of water and 50 ml of acetic acid, then 0.18 g of sodium nitrite, and the resultant mixture was stirred under refluxing and heating for 5 hours. After cooling, the reaction mixture was mixed with 200 ml of water, and the precipitated crystals were filtered and recrystallized from 50 ml of ethanol to give 4.7 g of N-(2, 6-diisopropyl-4-nitropheyl)-p-toluenesulfonamide. This compound was hydrolyzed in aqueous sulfuric acid to give 2.7 g of 2, 6-diisopropyl-4-nitroaniline.
