実験手順

14.8 g (62.3 mmol) 1-(3-chloro-phenyl)-1H-[1,2,4]-triazole-3-carboxylic acid methyl ester was taken up in 70 mL THF and treated with 40 mL 4M aqueous NaOH solution at RT for 12 h. The reaction mixture was diluted with water, THF was removed by distillation, ice water was added and the mixture was acidified with 4 M aqueous HCl solution. The precipitated was filtered off, washed with water and triturated with diethyl ether.
