3-Iodophenylboronic acid

反応条件: temp:75.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 5-Borono-2-chlorobenzoic acid (200 mg, 1 mmol), 3-iodophenylboronic acid (125 mg, 0.5 mmol), K2CO3 (207 mg, 1.5 mmol) and PdCl2(PPh3)2 (37 mg, 0.05 mmol) were dissolved in a mixture of toluene-MeOH (17 mL:1.7 mL) and heated at 75° C. for 3 hours. The mixture was filtered through celite washed with water and the solvent was evaporated in vacuo. The formed crude residue was acidified with 2 M HCl and extracted into EtOAc and dried over anhyd. Na2SO4, evaporated solvent in vacuo to obtain crude 3′-borono-4-chlorobiphenyl-3-carboxylic acid as a reddish brown solid. The crude product was used for the next step without further purification. The mixture was filtered through celite washed with water the solvent was evaporated in vacuo The formed crude residue extracted into EtOAc dried over anhyd Na2SO4, evaporated solvent in vacuo
