Participants

Reaction Steps

The product was prepared according to the general procedure for aminopyrazole synthesis (route A1) from 4-trifluoromethyl-benzoic acid methyl ester (3.0 g, 14.7 mmol, 1.0 eq), NaH (1.2 g, 29.4 mmol, 2.0 eq) and propionitrile (4.9 mL, 69.4 mmol, 4.7 eq). The crude product was extracted with DCM and used in the following step without further purification (3.2 g, yield: 96%).
