The reaction medium was heated at 60° C. for 7 hours and, after cooling to room temperature, was then poured into a water and ice mixture. The yellow precipitate formed was filtered off, reslurried in water and then dried over P2O5. 2.4 g of 2-[2-(4-nitro-2-methylphenylamino)ethylamino]ethanol (5) were obtained.
