Procedure

2,14-Dimethyl-8-hydroxy-2,6,10,14-tetrazapentadecane (17 g, 0.067 mol) synthesized in accordance with the method described in DE2616411, triethylamine (13 g, 0.13 mol), and methylene chloride (200 ml) were placed in a 500-ml four-necked round flask, and the mixture was cooled on ice. Dodecanoylchloride (29 g, 0.13 mol) was added dropwise over 1 hour to the flask while the contents of the flask were stirred under nitrogen. The mixture was stirred for 24 more hours at room temperature. The solid which precipitated was removed by filtration, after which water was added for washing. Methylene chloride was removed from the organic phase under reduced pressure. The residue was purified by column chromatography (packed with Kieselgel 60 (product of Merck), eluent:chloroform/methanol=7:1 (v/v)) to obtain 12.3 g of 4,8-bis(1-oxododecyl)-1,11-di(dimethylamino)-4,8-diazaundecane. Yield: 30 wt %.
