4-bromo-3-fluorobenzohydrazide

反応条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of compound 4-bromo-3-fluoro-benzoic acid methyl ester (1 g, 4.29 mmol), hydrazine hydrate (2.2 mL, 42.9 mmol) and MeOH (20 mL) was heated at 70° C. for overnight. Concentrated, diluted with EtOAc (300 mL) and washed with water (100 mL). The organic layer was dried over Na2SO4, filtered and concentrated give the desired product 2AR (0.9 g, 90%). Concentrated diluted with EtOAc (300 mL) washed with water (100 mL) The organic layer was dried over Na2SO4 filtered concentrated
