Yield:3365-85-3 77%

Reaction Conditions:

with 3% Pd/C;hydrazine in ethanolHeating;

Steps:

15
After stirring 3% by weight of a Pd/C catalyst to 1 equivalent of the compound of Formula o-2 in an ethanol solvent, 8 equivalents of an 80% hydrazine solution was slowly added dropwise at room temperature, followed by heating and stirring. After the reaction was completed, a tetrahydrofuran solvent was added, followed by Celite filtration to remove the catalyst. The filtrate was dried with a solvent through a vacuum distillation apparatus. After drying, the solid was filtered using an ethanol solvent to obtain 33.7 g (yield 77%) of a compound of formula o.
