Reaction Steps

In 12 ml of anhydrous ethanol were added 0.83 g (10.00 mmol) of 3-aminopyrazole and 1.92 g (15.00 mmol) of 2-acetyl-γ-butyrolactone. While stirring at room temperature, 0.1 ml of a boron trifluoride methanol complex were added to the resultant solution, and the mixture was then stirred for 4 hours under the same conditions. Solids deposited were collected by filtration, washed with ethanol and air-dried to obtain 1.34 g (yield: 69.4%) of the intended product.
