실험 절차

A solution of 5-chloro-3-trifluoromethylpyrazole (190.0 g, 1.11 mol) in 400 ml of methanol is treated with liquid bleach (5.25% NaOCl) for 3 hr. The reaction mixture is then extracted with ether, the combined ether extracts are acidified with HCl (300 ml), washed with brine, dried and concentrated to give 4,5-dichloro-3-trifluoromethylpyrazole, a light yellow solid, m.p. 58°-60° .
