Procedure

1.5 g (5.5 mmole) 5-Amino-4-nitro-1-(1-methyl-5-difluoromethoxy-3-pyrazolyl)pyrazole in 30 ml methylene chloride was treated with 0.74 g (5.5 mmole) sulfuryl chloride and the mixture stirred for 10 minutes at room temperature. It was then concentrated and the residue was recrystallised from diisopropyl ether/ethyl acetate. The mother liquor was concentrated and chromatographed (SiO2 /hexane/ethyl acetate 3:1).
