Yield:186309-73-9 92%
Reaction Conditions:
with boron tribromide in dichloromethane at 0 - 20; for 2 h;
Steps:
33 2-Amino-5-bromo-3-fluorophenol
To a suspension of 4-bromo-2-fluoro-6-methoxyaniline hydrobromide (1 equiv) in DCM (0.3 M) was added boron tribromide (2 equiv) in DCM at 0° C. The reaction mixture was stirred at room temperature for 2 h. After quenching, the reaction mixture was diluted with DCM then purified by silica gel chromatography (0 to 100% ethyl acetate in hexane) to give the title compound (92% yield). MS (ESI) m/z 205.9 [M+H]+.
