الإجراء التجريبي

2 g of 5-fluoro-2-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 10 hours and, after cooling to room temperature, was then poured into a water and ice mixture. The resulting medium was extracted with ethyl acetate and the organic phase was then concentrated under vacuum. 2.88 g of 4-(4-nitro-3-methylphenylamino)butan-2-ol (31) were obtained.
