Ethanolamine → HCID 22661647, compound

Participants

Reaction Steps

48 g of dodecylamine (259 mmol) and 1.7 ml of ethanolamine (29 mmol) were dissolved in 100 ml of ethanol, after which 8.6 g of paraformaldehyde (287 mmol) were added and the mixture was stirred. The turbidity caused by 1,3,5-tridodecyl-1,3,5-triazacyclohexane was redissolved every now and again by addition of ether. After about 1 day, all the paraformaldehyde had dissolved. The solvent was then removed on a rotary evaporator, the residue was dissolved in a little toluene and the product was then again freed of solvent under reduced pressure. This left 55 g of a viscous colorless product which, according to NMR spectroscopy, consisted of about 75 mol % of 1,3,5-tridodecyl-1,3,5-triazacyclohexane and 25 mol % of 1,3-didodecyl-5-(2-hydroxyethyl)-1,3,5-triazacyclohexane and a little toluene.
