Reaction Steps

4.6 g (0.05 mol) of N-ethylcarbamoyl fluoride were added to a mixture of 7 g (0.05 mol) of 1-tert.-butyl-4-hydroxypyrazole, 10.4 g (0.075 mol) of potassium carbonate and 100 ml of acetonitrile. The mixture was stirred for a further 3 hours at 20° C. It was then filtered under suction. The filtrate was concentrated by evaporation in vacuo. 9 g (85% of theory) of 1-tert.-butyl-pyrazol-4-yl N-ethylcarbamate were obtained in the form of beige crystals with a melting point of 77° C.
