The reaction of 1, 4-bis(p-toluenesulfonyl)-1, 4, 7- triazacyclononance with the bis (bromomethyl) compounds 4a-4c in CH~3CN/K~2CO~3 afforded the N-p-toluenesulfonyl substituted bis (1, 4, 7-triazacyclononanylmethyl) compounds 5a-5c. Treatment of compounds 5a-5c with conc. H~2SO~4 followed by conc. HCl gave the hydrochloride of 6a-6c. Compounds 5a-5c and 6a-6c were identified by elemental analysis and spectral analysis (IR、^1H NMR、^1^3C NMR、MS).
