実験手順

To a stirred solution of methyl (3R,4S)-1-[(Z)-1-(methylthio)-2-nitrovinyl]-4-[(3R)-3-phenylpyrrolidin-1-yl]carbonylpiperidine-3-carboxylate (81.0 mg, 0.000187 mol) in ethanol (3.0 mL, 0.051 mol) was added piperidine (92.8 uL, 0.000934 mol). The reaction mixture was heated to reflux (oil bath temperature: 85° C.) for 17 h 45 min. The reaction mixture was concentrated in vacuo. The residue was purified by Combiflash with 0-8% MeOH/CH2Cl2 to give the product as a yellow solid (62 mg, 71% in yield). MS (ESI): (M+H)+=471.1.
