Procedure

To a solution of 10 g (52 mmol) 2,5-dichloronitrobenzene in 40 ml butanol was added 6,5 g (104 mmol) ethanolamine, and the mixture was refIuxed for 20 h. The reaction mixture was evaporated in vacuo. The residue was recrystallized (toluene) to give 8.1 g (75%) N-(2-hydroxyethyl)-4-chloro-2-nitroaniline. M.p. 98°-100 ° C.
