Participants

Reaction Steps

A solution of trimethylboroxine (83 mg), tris(dibenzylideneacetone)dipalladium (10 mg), Xantphos (18 mg), potassium carbonate (165 mg) and 3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-5-methyl-4-trifluoromethylthiopyrazole (250 mg) in dioxane was heated in a microwave for 20 minutes at 130° C. in a 10 ml sealed Pyrex glass tube. The reaction mixture was cooled to room temperature then diluted with ethyl acetate and filtered over Celite. The organic filtrate was washed with water, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure to give a residue that was purified by chromatography (SiO2, heptane/EA) to afford the title compound as a white solid. MS (ES): M/Z [M+NH4]=417. 1H NMR: (400 MHz, CDCl3): 2.13 (s, 3H), 2.26 (s, 3H), 7.60 (bs, 1H) and 7.73 (bs, 1H). 19F NMR (376 MHz, CDCl3): −44.25 (s, 3F) and −63.63 (s, 3F).
