A solution of 87.2 g of 1,10-diamino-4,7-diazadecane in 500 ml of toluene was admixed with 72.3 g of a 40% aqueous glyoxal solution, and the mixture was refluxed, with a water separator fitted, for 3 hours. When the solution was cooled, a solid precipitated out which was filtered off with suction, washed three times with 50 ml of toluene each time and dried under reduced pressure. This gave 34.9 g of pale yellow needles.
