Reaction Steps
38.7 g of [1-(3-chloropyridin-2-yl)-5-hydroxy-5-(trichloromethyl)-4,5-dihydro-1H-pyrazol-3-yl]-methyl acetate were dissolved in 200 ml of methyl tert-butyl ether, and 12.6 g of oxalyl chloride were added dropwise within 2 h (vigorous evolution of gas). The mixture was stirred at 25° C. for a further 5 h and concentrated completely under reduced pressure.
