Reaction Steps

Into a 100-mL round-bottom flask, was placed a solution of pyrrolidine (5.8 mL, 70.30 mmol) in CH3CN (30 mL). Triethylamine (9.8 mL, 70.17 mmol) and 1H-pyrazole-1-carboximidamide hydrochloride (10.2 g, 69.59 mmol) was added to the reaction. The reaction mixture was stirred overnight at 60° C. The product was collected by filtration to yield 7.5 g (71%) of the title compound as a white solid.
