Reaction Steps

A mixture of (S)-2-(5-ethynyl-1H-benzoimidazol-2-yl)-piperidine-1-carboxylic acid benzyl ester (41 mg, 0.115 mmol) and dichloro(p-cymene) ruthenium (II) dimer (5 mg) is purged with N2. AcOH (1 mL) is added and the mixture is stirred at room temperature overnight and concentrated in vacuum to dryness. The residue is purified by flash column chromatography on silica gel (EtOAc/hexanes 5% to 100%) and repurified by reverse phase HPLC using a gradient of CH3CN/water to afford the title compound (5.9 mg, 7%).
