Reaction Steps

5 g of 2,4-dimorpholino-6-(4-oxo-2,2,6,6-tetramethylpiperidin-1-yl)-1,3,5-triazine (product from Example 21) are hydrogenated in 100 ml of tetrahydrofuran at 60° and a pressure of 100 bar until the reaction stops using Raney nickel as the catalyst. The reaction mixture is filtered, the solution is evaporated and the residue is recrystallized from 20 ml of toluene. The above substance is produced as white crystals which melt at 202°-204°.
