Acetonitrile--water (1/1) → HCID 24785733, compound

Participants

Reaction Steps

Sodium periodate (20 mg) and ruthenium chloride (3 mg) were added to a solution of 3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-5-methyl-4-trifluoromethylthiopyrazole (100 mg), that is described in Example 1, in a mixture of acetonitrile-water (4:1). The reaction mixture was stirred overnight whereupon the mixture was diluted with ethyl acetate and filtered over silica gel. The organic filtrate was washed with water, dried over anhydrous magnesium sulfate, filtered over Celite and concentrated under reduced pressure to give the title compound as a white solid (73 mg, 68%). MS (ES): M/Z [M+H]=452. 1H NMR: (400 MHz, DMSO-d6): 2.46 (s, 3H) and 7.87 (s, 2H). 19F NMR (376 MHz, DMSO-d6): −63.77 (s, 3F) and −79.83 (s, 3F).
