methyl (E)-3-(2-amino-4-fluorophenyl)prop-2-enoate

反応条件: temp:65.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of (E)-methyl 3-(2-amino-4-fluorophenyl)acrylate (30.38 g, 156 mmol) in THF (400 mL) and 3M hydrochloric acid (400 mL) was heated at 65° C. for 20 h. The mixture was cooled to RT and poured onto ice. The resulting precipitate was filtered, washed with copious amounts of water and dried in vacuo to give 20.65 g (81%) of a light-yellow amorphous solid. m/z=164 (M+1). The mixture was cooled to RT poured onto ice The resulting precipitate was filtered washed with copious amounts of water dried in vacuo

反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a mixture of 2-bromo-5-fluoroaniline (35.00 g, 184 mmol, Aldrich), palladium (II) acetate (2.06 g, 9.18 mmol, Strem) and tri(o-tolyl)phosphine (5.60 g, 18.40 mmol; Strem) in acetonitrile (350 ml) at RT was added methyl acrylate (33.00 ml, 365 mmol, Aldrich) and triethylamine (64.00 ml, 460 mmol, Aldrich). The reaction was heated at 80° C. for 24 h. The reaction mixture was diluted with EtOAc (500 mL) and the resulting colorless crystalline solid was filtered and washed with EtOAc. The organic solution was concentrated to dryness and the solids were slurried in 10% EtOAc/hexane at 60° C. for 1 h. The slurry was cooled to RT and filtered. The solid was washed with 10% EtOAc/hexane and sucked dry with air to give 18.30 g (51%) of a light-yellow crystalline solid. m/z=195.9 (M+1). the resulting colorless crystalline solid was filtered washed with EtOAc The organic solution was concentrated to dryness The slurry was cooled to RT filtered The solid was washed with 10% EtOAc/hexane sucked dry with air
