Versuchsvorschrift
A mixture of 5′-(cyclohexanecarbonyl-amino)-2′-chloro-biphenyl-4-carboxylic acid ethyl ester (200 mg) in ethanol (15 ml) and 1M sodium hydroxide (7.5 ml) was stirred at 20 C for 18 h. The ethanol was then evaporated and the residue acidified. The solid thus formed was collected by filtration and dried (176 mg).
