摘要:
The invention relates to a process for preparing an optionally substituted 4-benzimidazol-2-ylmethylamino)-benzamidine, characterized in that (a) an optionally correspondingly substituted diaminobenzene is condensed with 2-[4-(1,2,4-oxadiazol-5-on-3-yl)-phenylamino]-acetic acid, (b) i) the product thus obtained is hydrogenated and ii) optionally the amidino group is carbonylated, without isolating the intermediate product of the hydrogenation beforehand; as well as a process for preparing a salt of an optionally substituted 4-(benzimidazol-2-ylmethylamino)-benzamidine, wherein (a) an optionally correspondingly substituted diaminobenzene is condensed with 2-[4-(1,2,4-oxadiazol-5-on-3-yl)-phenylamino]-acetic acid, (b) the product thus obtained is hydrogenated, and (c) i) optionally the amidino group is carbonylated and ii) without prior isolation of the intermediate product of the carbonylation the desired salt is isolated.
