合成路线1

The condensation of 2-(chloromethyl)-1,4-dioxaspiro[4,5]decane (I) with the sodium salt of phthalimide (II) in hot DMF affords the N-substituted phthalimide (III). Subsequent phthaloyl group hydrazinolysis gives the primary amine (IV). Finally, condensation of amine (IV) with S-methyl pseudothiourea sulfate (V) leads to the title guanidine derivative

In a different method, acetylation of 3-amino-1,2-propanediol (I) yields the amide diol (II). Ketalization of cyclohexanone (III) with diol (II) furnishes the spiro dioxolane (IV). The acetamide function of (IV) is then hydrolyzed to amine (V) employing aqueous hydrazine. Amine (V) is condensed with N,N'-di-(carbobenzoxy)-N''-(trifluoromethylsulfonyl)guanidine (VI) to produce the protected guanidine (VII). The N-carbobenzoxy groups of (VII) are finally removed by hydrogenolysis over Pd/C. Alternatively, amine (V) is condensed with cyanogen bromide to produce the cyanamide (VIII). Then, reaction of cyanamide (VIII) with ammonium chloride in aqueous ammonia furnishes the title guanidine compound
