1,8-Octanediamine, 4-(aminomethyl)- → 1,8-Bis[N-(2,4-bis[N-octyl-N-(2,2,6,6-tetramethylpiperid-4-yl)amino]-1,3,5-triazin-6-yl)amino]-4-[N-(2,4-bis[N-octyl-N-(2,2,6,6-tetramethylpiperid-4-yl)amino]-1,3,5-triazin-6-yl)aminomethyl]octane

Participants

Reaction Steps

A solution of 28.3 g of 2-chloro-4,6-bis[N-octyl-N-(2,2,6,6-tetramethyl-4-piperidyl)amino]-1,3,5-triazine [prepared as described in Preparation 2(b)] and 1.0 g of 1,8-diamino-4-aminomethyloctane in 200 ml of xylene was refluxed for 10 hours. It was then treated as described in Example 1 to give a residue, which was purified by column chromatography through silica gel, eluted with a 20:1:1 by volume mixture of ethyl acetate, ethanol and triethylamine, to give the desired Compound No. 14, in the form of crystals melting at 55°-60° C.
