Procedure
9 g of the ester according to (b) are dissolved in 100 ml aqueous ethanol. 1.8 g potassium hydroxide dissolved in 25 ml water are added and the mixture refluxed for 8 hours. The ethanol is evaporated and the remaining aqueous phase acidified by addition of mineral acid. The acid is extracted in ethyl ether.
