Reaction Steps

A flask charged with trifluoromethanesulfonic acid 6-[5-((S)-2-methyl-1-methylcarbamoyl-propylcarbamoyl)-furan-2-yl]-pyridin-3-yl ester (50 mg, 0.11 mmol), phenylboronic acid (27 mg, 0.22 mmol), palladiumtetrakistriphenylphosphine (13 mg, 0.01 mmol), and potassium carbonate (61 mg, 0.44 mmol) is flushed with argon. Toluene (2 mL), ethanol (0.5 mL), and water (1 mL) are added and the reaction is stirred at 100° C. for 2 hours. The reaction is cooled to room temperature, ethyl acetate (10 mL), is added and the mixture washed with water (10 mL), brine (10 mL), and dried over MgSO4. The solution is filtered and evaporated in vacuo to give an oil that is purified by preparative HPLC. 5-(5-Phenyl-pyridin-2-yl)-furan-2-carboxylic acid ((S)-2-methyl-1-methylcarbamoyl-propyl)-amide is obtained as a white solid, 16 mg, 38%, LC/MS ESI m/z (M+H)+=377.43.
