実験手順

To a solution of 1-[1-(4-Chloro-3-methyl-benzyl)-piperidin-4-yl]-5-oxo-pyrrolidine-2-carboxylic acid [3-bromo-5-(1-methyl-1H-tetrazol-5-yl)-phenyl]-amide (400 mg) in MeOH (20 ml) was added triethylamine (140 μl), DMF (5 ml), and [1,1′-bis(diphenylphosphino)-ferrocen]palladium (II) chloride (50 mg) and the reaction stirred for 2 d at 80° C. under a 3 bar CO atmosphere. The reaction mixture was filtered and the filtrate concentrated in vacuum. The residue was partitioned between water and EtOAc and the organic layer was then separated, dried and concentrated in vacuum. The residue was purified by flash chromatography (DCM: MeOH 100:0 to 95:5 gradient) to give the title compound (400 mg). Rf=0.37 (95:5 DCM:MeOH).
