Yield:5407-68-1 93%
Reaction Conditions:
with nitric acid in acetic anhydride; for 1 h;
Steps:
2
The compound 2 (56 g, 0.4 μM) and second grade acid anhydride (40.1 g, 0.4 μM) adding 3 flasks, slowly dropping 65% of concentrated nitric acid (38.8 g, 0.4 μM), stirring 1 h, the reaction liquid is poured into the 500 ml ice water, 15% sodium hydroxide solution to adjust pH to 6 - 7, dichloromethane is used for extraction, anhydrous magnesium sulfate drying. Evaporate the solvent, to obtain compound 3 (64.4 g, pale yellow liquid, yield 93%).
