Reaction Steps

A suspension of sodium ethoxide (0.34 g) in ethanol was added to a stirred solution of 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-methylsulfinyl-1H-pyrazole-3-carboxaldehyde oxime (2.0 g) in ethanol. 2-lodopropane (1 ml) was then added and the mixture stirred overnight at 20° C. and evaporated. The residue (in dichloromethane) was water-washed, dried (magnesium sulfate), concentrated and purified by chromatography on silica gel to give 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-methylsulfinyl-1H-pyrazole-3-carboxaldehyde O-(isopropyl)oxime (0.35 g), m.p. 128-130° C. Compound 24.
