実験手順

To N2-[(1S)-1-(4-bromophenyl)-2,2,2-trifluoroethyl]-N-[(1S)-1-cyano-2-(4-iodophenyl)ethyl]-L-leucinamide (1 eq) in DMSO (0.3 M) were added methane sulfonic acid sodium salt (2 eq) and copper iodide (3 eq) and the mixture was stirred at 100° C. for 2 h. The reaction mixture was cooled and diluted with EtOAc. The organic layer was washed with brine and water, dried over Na2SO4, filtered and concentrated. The crude compound was purified by automated SiO2 flash chromatography system using solvent gradient of 40% EtOAc/Hex to 100% EtOAc/Hex.
