실험 절차
74.0 g (0.549 mol) of sulfuryl chloride dissolved in 200 ml of carbon tetrachloride were added slowly dropwise to a solution of 128.9 g (0.5 mol) of 3-(4-chlorophenyl)-5-difluoromethoxy-1-methyl-1H-pyrazole in 500 ml of carbon tetrachloride, the ensuing reaction being exothermic with evolution of gas. After the end of the reaction the mixture was stirred at about 20° C. for a further 2 h. The reaction solution was then washed with about 300 ml each of water, saturated sodium hydrogen carbonate solution and saturated sodium chloride solution, and then dried and concentrated. Yield: 139.3 g; 1H-NMR (270 MHz, in CDCl3): δ [ppm]=7.79 (d, 2H), 7.43 (d, 2H), 6.70 (t, 1H), 3.85 (s, 3H).
