HCID 15100245, compound → 1H-Imidazole-5-sulfonamide, 1-methyl-N-(3-(4-morpholinyl)propyl)-, monohydrochloride

Participants

Reaction Steps

1 g (2.8 mmol) of N-(3-morpholinopropyl)-4-chloro-1-methyl-5-imidazolesulfonamide from Example 31 is dissolved in 130 ml of 25% strength aqueous ethanol, 0.3 g of Pd/C catalyst is added and the mixture is hydrogenated with shaking at an initial pressure of 3.45 bar until absorption of hydrogen is complete. The catalyst is filtered off. The filtrate is concentrated in vacuo and the residue is recrystallized from ethanol. The title compound of melting point 205°-206° C. is obtained in a yield of 0.8 g (88% of theory).
