実験手順
16.7 g (46.5 mmol) of 5-chloro-N-(3-morpholino-1-propyl)-1-methyl-4-imidazolesulfonamide hydrochloride from Example 32 are hydrogenated at 25° C. and 3.45 bar in the presence of 3 g of Pd/C catalyst in 250 ml of water. The residue remaining after filtration and evaporation in vacuo is converted into the free base using saturated potassium carbonate solution, extracted with dichloromethane and recrystallized from dioxane/diisopropyl ether in order to give the crystalline title compound, identical with that as in Example 7.
