Versuchsvorschrift

The mixture of 1.86 g of 3-(pentafluoroethyl)-1H-pyrazole and 0.60 g of paraformaldehyde was stirred at 130° C. for 5 hours. After the reaction mixture was cooled to room temperature, acetone was added. The mixture was filtered. The filtrate was concentrated under reduced pressure to obtain 1.98 g of 3-(pentafluoroethyl)-1H-pyrazole-1-ylmethanol.
