N-(2-氨基乙基)-4-氟苯甲酰胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 7.7 g (0.05 mol) of methyl 4-fluorobenzoate and 10 ml (0.15 mol) of ethylene diamine are heated to 130° (bath temperature) for 2 hours. The mixture is poured on to ice/hydrochloric acid and extracted with ethyl acetate in order to remove the neutral constituents. The aqueous phase is made alkaline with sodium hydroxide solution and extracted several times with chloroform. After drying and concentrating the chloroform extracts, the residue (7.6 g) is recrystallized from ethyl acetate/hexane, the being obtained N-(2-aminoethyl)-4-fluorobenzamide, m.p. 57°-60°. The hydrochloride melts at 214°-216°. extracted with ethyl acetate in order to remove the neutral constituents extracted several times with chloroform After drying concentrating the chloroform the residue (7.6 g) is recrystallized from ethyl acetate/hexane
