  • Process For The Preparation Of Prothioconazole And Intermediates Thereof
    Publication number: 20240025865
    Abstract: The present invention is directed to a process for the preparation of a hydrazine derivative by reaction of the corresponding oxirane with hydrazine, that uses as only solvent toluene. The process provides excellent yields and purities and allows to proceed without purification in a one-pot scheme. Toluene additionally reduces the excess of hydrazine needed to complete the reaction, significantly reducing the waste treatment costs and even allows the hydrazine to be recycled into the reaction.
