Reaction Steps

A 250 mL flask containing the Methyl 7-amino-2-methylpyrazolo[1,5-a]pyrimidine-6-carboxylate (2.1 g, 20 mmol), EtOH (55 mL), and hydrazine hydrate (20 mL) was heated to reflux for 6 hours. The mixture was allowed to cool to room temperature. The precipitated solid was filtered and washed with water (2×10 mL) to provide Compound (10-1) as a white solid.
