Mode opératoire

2 g of 2-fluoro-5-nitrotoluene were added to a solution of 20 ml of N-methylpyrrolidinone, 1.38 g of 4-amino-2-butanol and 1.57 g of triethylamine. 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. 2.38 g of 4-(4-nitro-2-methylphenylamino)butan-2-ol (27) were obtained.
