1,4,7,10,13-Pentaazacyclopentadecane → HCID 86750557, compound

Participants

Reaction Steps

A solution of 1,4,7,10,13-pentaazacyclopentadecane prepared as in Example 1E (2.0 g, 9.3 mmole) and anhydrous manganese(II) chloride (1.2 g, 9.3 mmole) in anhydrous methanol (50 ml) was refluxed under a dry nitrogen atmosphere for 3 h. The solution was filtered and the solvent removed in vacuo. The resulting solid was recrystallized from ethanol-ethyl ether to give 2.79 g (88% yield) of the product as an off-white crystalline solid: FAB mass spectrum (NBA) m/z (relative intensity) 340 (M+, 2), 305/307 ((M-Cl)+ 100/45)); Anal. Calcd. for C10H25Cl2MnN5 : C, 35.17; H, 7.38; Cl, 20.76; N 20.60. Found: C, 34.95; H, 7.31; Cl, 20.49; N, 20.22.
