Versuchsvorschrift
7.00 g (27.7 mmol) 2-(3-chloro-phenyl)-2H-tetrazole-5-carboxylic acid ethyl ester was dissolved in 50 mL THF and 50 mL water and treated with 2.33 g (55.4 mmol) LiOH at RT for 14 h. The reaction mixture was concentrated and acidified with 1 M aqueous hydrochlorid acid. The precipitate was filtered off, washed with water and dried.
