To a 4 mL vial equipped with a magnetic stir bar were added 4-bromo-3,5-dimethyl-1H-pyrazole (50 mg, 0.286 mmol), 2-bromo-N-isopropylacetamide (51.4 mg, 0.286 mmol), K2CO3 (118 mg, 0.857 mmol), and acetonitrile (2 mL). The contents of the vial were stirred to give a white suspension. The vial was heated in a sand bath to 70° C. for 24 hours. The reaction mixture was subsequently partitioned between water (10 mL) and ethyl acetate (15 mL). The layers were separated, and the aqueous layer was back-extracted with ethyl acetate (15 mL). The combined organic layers were concentrated to give the title compound as a white solid, which was used without further purification (80 mg).
