Participants

Reaction Steps

1.0 Gram (0.0027 mole) of 4-[(1,3-dimethyl-5-phenoxypyrazol-4-yl)methyleneaminooxymethyl]benzoic acid, 0.25 g (0.0027 mole) of phenol and 0.7 g (0.0027 mole) of triphenylphosphine were added to 50 ml of ether, and the resulting mixture was stirred. To this solution was added 0.47 g (0.0027 mole) of diethyl azodicarboxylate, and the resulting solution was heated under reflux for 3 hours. After completion of the reaction, the ether layer was filtered, and ether was removed by evaporation to obtain an oily product. This oily product was column-chromatographed on silica gel to obtain 0.9 g of the desired compound.
