Sodium Carbonate → 6-(4-Chlorophenyl)benzo[d][1,3]dioxole-5-carbaldehyde

Participants

Reaction Steps

To a solution of 6-bromobenzo[d][1,3]dioxole-5-carbaldehyde (4.6 g), 4-chlorophenylboronic acid (3.78 g) and tetrakis(triphenylphosphine)palladium(0) (0.232 g) in toluene (80 mL) and methanol (30 mL) was added 2N aqueous Na2CO3 (30 mL). The mixture was stirred at reflux overnight. The mixture was diluted with ether (400 mL) and washed with water, brine and dried over Na2SO4. After filtration and concentration of the solvent, the residue was loaded on a column and eluted with 3% ethyl acetate in hexane to give the product.
