Mode opératoire

2 g of 5-fluoro-2-nitrotoluene were added to a solution of 20 ml of N-methylpyrrolidinone, 1.63 g of 2-aminoethoxyethanol and 2.14 g of K2CO3. The reaction medium was heated at 60° C. for 12 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. 1.9 g of 2-[2-(4-nitro-3-methylphenylamino)ethoxy]ethanol (15) were obtained after purification on a column of silica.
