Allyl chloroformate → HCID 13373348, compound

Participants

Reaction Steps

5.5 g of Compound [II] was dissolved in 30 ml of dioxane, and 4.2 g of allyl chloroformate was added to the solution. The mixture was allowed to react for 8 hours under refluxing. After completion of the reaction, the solvent was distilled off, and hexane and a potassium carbonate aqueous solution were added to the residue to form crystals. Thus, 3.4 g of allyl N-(5-t-butyl-3-pyrazolyl)carbamate was obtained. This compound was recrystallized from hydrous methanol and found to have a melting point of 131° C. to 132° C.
