Procedure
A mixture of 5-amino-4-chlorosulphonyl-1-(2,6-dichloro-4-trifluoromethylphenyl)-3-trifluoromethylpyrazole (1.2 g) and dimethylamine (17.6 ml of a 40% aqueous solution) was heated on a steambath for 1 hour, cooled, and poured onto crushed ice (50 g) to give a brown solid. This solid was filtered, dried, and recrystallized from toluene to give 5-amino-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-(N,N-dimethylsulphamoyl)-3-trifluoromethylpyrazole (0.8 g) as light brown crystals, m.p. 177.6°-178.6° C.
