Procedure

13 g (27 mmol) of 1,6-bis(5-chloro-1-methyl-4-imidazolesulfonamido)hexane from Example 47 in 250 ml of 1N sodium hydroxide solution are hydrogenated over 3 g of 10% strength Pd/C catalyst while shaking at an initial pressure of 3.45 bar until absorption of hydrogen is complete. After separating off the catalyst, the filtrate is evaporated in vacuo. The residue was recrystallized from water/methanol in order to give the title compound as colorless crystals of melting point 153°-154° C.
