Reaction Conditions:
with iron(II) nitrate;pyrographite in ethanol; for 1 h;Reagent/catalyst;
Steps:
3 Synthetic method 12
General procedure: Ethyl 3-oxo-3-phenylpropionate (100 mg, 0.52 mmol), thiourea (59.4 mg, 0.78 mmol), ferrous nitrate (28.06 mg, 0.156 mmol) and activated carbon (200 mg) were added to the reaction flask , followed by adding 30 mL of anhydrous ethanol as a solvent, and stirring for 1 hour under an oxygen atmosphere.After completion of the reaction, filter and evaporate the solvent under reduced pressure; add 50 mL of water and extract with ethyl acetate; combine the organic phases and wash with saturated brine; dry over anhydrous sodium sulfate and evaporate the organic solvent under reduced pressure to obtain a crude product; the crude product After separation and purification, 104.1 mg of white solid was obtained with a yield of 80.5%.
