Dimethylformamide → 6-Bromo-2,4'-difluoro-3-isopropoxybiphenyl-4-carbaldehyde

Participants

Reaction Steps

A mixture of 6-bromo-2,4′-difluoro-3-hydroxybiphenyl-4-carbaldehyde (3.50 g), 2-iodopropane (5.70 g), potassium carbonate (3.09 g), and DMF (15 mL) was stirred at 50 C for 1 hour. The reaction mixture was poured to water, followed by extraction with ethyl acetate twice. The organic layer was separated, then washed with saturated saline, and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound (2.94 g)
