Participants

Reaction Steps

A solution of 2-phenylmethyl-1,4,7,10,13-pentaazacyclopentadecane prepared as in Example 6D (1.5 g, 4.9 mmole) and anhydrous manganese(II) chloride (0.62 g, 4.9 mmole) in anhydrous methanol was refluxed under a dry nitrogen atmosphere overnight. The solution was filtered and the solvent removed in vacuo. The yellow gummy solid was purified by stirring vigorously in acetone to give 1.89 g (89% yield) of the product as a white solid: FAB mass spectrum (NBA) m/z (relative intensity) 395/397 [(M-Cl)+, 100/31]; Anal. calcd. for C17H31Cl2 nN5 : C, 47.34; H, 7.24; Cl, 16.44; N, 16.24. Found: C, 46.84; H, 7.51; Cl, 16.38; N, 15.86.
