Reaction Steps

The mixture of 0.62 g of 3-t-butyl-4-chloro-1H-pyrazole, 0.24 g of paraformaldehyde and 0.10 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. Hexane was added to the residue obtained by concentration of the filtrate under reduced pressure, as a result, a crystal was formed. The crystal was collected to obtain 0.82 g of 3-t-butyl-4-chloro-1H-pyrazole-1-ylmethanol.
