Yield:84478-89-7 100%
Reaction Conditions:
with sulfuric acid;nitric acid at 0;
Steps:
4.9
Intermediate 8 (65 g, 0.318 mol) was suspended in concentrated sulphuric acid (24.1 mls) and stirred in an ice bath. The nitrating mix of sulphuric acid (24.1 ml) and nitric acid (24.1 mls) was added slowly and turned the reaction yellow. Stirring continued until the reaction appeared to solidify. Water was added and the product was collected by filtration to yield the desired product with a small amount of water still present (81.47 g, 102%).
