Sodium Carbonate → 6-Phenylpyridine-2-carboxylic Acid

Participants

Reaction Steps

Preparation H9, Step 1: 6-Bromopicolinic acid (1.0 g) was dissolved in 1,2-dimethoxyethane (15 mL) prior to the addition of palladium tetrakistriphenylphoshine (572 mg), 2M Na2CO3 (5 mL), and phenyl boronic acid (905 mg). The resulting solution was heated at reflux for 48 h. After cooling, 1N HCL was added to adjust the pH<4. A white precipitate was formed and was removed by filtration. A small portion of the filtrate was purified by reverse phase HPLC (gradient elution, water/acetonitrile/TFA) to afford 6-phenylpicolinic acid (25 mg). MS found: (M+H)+=200.1.
