Reaction Conditions:
with nitric acid;N,N-dimethyl-formamide;sodium nitrite at 45;Reagent/catalyst;Solvent;Temperature;
Steps:
6 Example 6:
Nitric acid (126 g, 2 mol) and sodium nitrite (0.04 mol) were added dropwise, and the reaction temperature was controlled at 45 °C, and the reaction mixture was stirred and reacted with dimethylformamide (15 mol). Completely poured into ice water, concentrated to a small volume, cooling, standing, until the solid precipitation, Filtration, ice water washing, collecting product 165.3g, molar yield 99.0%, HPLC greater than 99.5%.
