Participants

Reaction Steps

The ketone thus formed was dissolved in 150 ml of ethanol containing 32 g of hydrazine. The reaction mixture was heated at reflux for twelve hours, and then cooled to room temperature. Removal of the solvent by evaporation under reduced pressure provided a solid residue, which when triturated with 250 ml of petroleum ether, filtered and air dried, was identified as 12.5 g of 3-tert.-butyl-5-amino-1H-pyrazole.
