合成路线1
该中间体在本合成路线中的序号：AGN-192614Several degradation products and metabolites of brimonidine have been synthesized: 1) The reaction of 5-bromoquinoxalin-6-amine (I) with cyanamide (II) and HCl in refluxing dioxane gives N2-(5-bromoquinoxalin-6-yl)guanidine (AGN-191383). 2) The reaction of AGN-191383 with 1,1'-oxalyldiimidazole (III) and dimethylaminopyridine (DMAP) in pyridine yields 2-(5-bromoquinoxalin-6-ylimino)imidazolidine-4,5-dione (AGN-192597). 3) The reaction of AGN-191383 with sodium iodoacetate (IV) in DMSO and then acidification with HCl affords 2-[N2-(5-bromoquinoxalin-6-yl)guanidino]acetic acid (AGN-192614).
