12.12 g (0.045M) of N-benzenesulfonylpiperidine-4-carboxylic acid were dissolved in 250 ml of water with the addition of 22.5 ml of 4N NaOH at 50° C. Thereafter, 2.94 g (0.045M) of ZnSO4.7H2O, dissolved in 100 ml of water, was slowly added at 50° C. After the mixture had been stirred for 3 1/2 hours at 50° C., the resulting pH was 7.3. The mixture was then stirred at room temperature, and the product was filtered off under suction, washed and dried. 15.8 g of a product which contained 1.05 moles of Zn per mole of starting acid resulted.
