N-(3-Aminopropyl)morpholine → 1H-Imidazole-4-sulfonamide, 1-methyl-N-(3-(4-morpholinyl)propyl)-

Participants

Reaction Steps

Analogously to Example 7, 10 g (51 mmol) of 1-ethyl-4-imidazolesulfonyl chloride from Example C-2 are reacted with 7.5 ml (51 mmol) of 3-morpholinopropylamine in 200 ml of acetonitrile and the mixture is correspondingly worked up. The hydrochloride thus obtained is dissolved in methanol and converted into the free base by means of an equivalent amount of methanolic sodium methylate solution. The oil remaining after evaporating in vacuo crystallizes after addition of an equimolar amount of ethanolic fumaric acid as the hydrogenfumarate of melting point 148°-149° C.
