tert-butyl 5-bromo-2-fluorobenzoate

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

実験手順: To tert-butyl 5-bromo-2-fluorobenzoate (1.26 g) in dimethoxyethane (22.9 ml) solution, tris(dibenzylideneacetone)dipalladium (0.10 g), 2-(di-tert-butylphosphino)-2′-methylbiphenyl (0.14 g), tripotassium phosphate (1.07 g), and 1-nitropropane (0.82 ml) were added, the mixture was stirred at room temperature for 1 minute, then the mixture was stirred under heating and reflux for 15 hours. The insoluble compound was filtered out, then the filtrate was concentrated. The residue was purified by silica gel column chromatography (hexane/ethyl acetate, ethyl acetate: 0 to 10%) to obtain the title compound (392 mg). the mixture was stirred under heating reflux for 15 hours The insoluble compound was filtered out the filtrate was concentrated The residue was purified by silica gel column chromatography (hexane/ethyl acetate, ethyl acetate: 0 to 10%)
