実験手順
To a solution of (3R*,5S*)3-{Cyclopropyl-[1-(3-methoxy-propyl)-1H-indol-3-ylmethyl]-carbamoyl}-5-(2-nitro-benzenesulfonylamino)-piperidine-1-carboxylic acid tert-butyl ester (400 mg, 0.60 mmol), 2-(2-hydroxyethyl) isoindole-1,3-dione (171 mg, 0.9 mmol), and PPh3 (315 mg, 1.2 mmol) in THF is added DEAD (208 mg, 1.2 mmol) at room temperature, then the mixture is stirred at 60° C. After 13 h, the reaction mixture is quenched by H2O (20 mL) and extracted with EtOAc (50 mL). The organic phase is successively washed with 5% aqueous KHSO4, H2O, and brine, then dried over Na2SO4 and concentrated in reduced pressure. The residue is purified by silica gel column chromatography to afford the title compound as yellow amorphous material. MS: 843 [M+H]+; tR (HPLC, ACQUITY UPLC™ BEH C18 1.7 μm, 50×2.1 mm; 5% CH3CN+0.1% TFA/H2O+0.1% TFA for 0.5 min then 5-100% CH3CN+0.1% TFA/H2O+0.1% TFA for 5 min then 100% CH3CN+0.1% TFA for 1.5 min, flow 0.5 ml/min): 4.41 min.
