Reaction Conditions

Reaction Steps

The mixture of 1.15 g of 3-i-propyl-1H-pyrazole, 0.94 g of paraformaldehyde and 0.14 g of triethylamine was stirred at 130° C. for 7 hours. After the reaction mixture was cooled to room temperature, acetone was added to the reaction mixture. The mixture was filtered. The filterate was concentrated under reduced pressure. Hexane was added to the residue, and then crystalline was formed. The crystalline was collected to obtain 1.28 g of 3-i-propyl-1H-pyrazole-1-ylmethanol.
