Participants

Reaction Steps

A solution of 379 g (2 mol) of 2-nitrophenylsulphenyl chloride in 2 l of methylene chloride is added to a solution of 210 g (2 mol) of bis(2-hydroxyethyl)amine and 202 g (2 mol) of triethylamine in 3 l of methylene chloride in the course of 90 minutes, the temperature rising from 21° to 34°. The mixture is subsequently stirred at room temperature for 2 hours and is left to stand overnight and the solution is washed six times with 1 l of water each time, dried with sodium sulphate and concentrated in vacuo. The residue is an orange-yellow solid product of melting point 82°-86°, which is sufficiently pure for further reaction. Yield: 499 g.
