Reaction Steps
Ethyl 5-amino-1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole-4-carboxylate, was diazotised and treated with phosphorous acid to give ethyl 1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazole-4-carboxylate, m.p. 70°-73°. This was reduced to [1-(2,6-dichloro-4-trifluoromethylphenyl)-1H-pyrazol-4-yl]methanol, m.p. 57°-59°
