実験手順
To a solution of (3R*,5S*)-3-{Cyclopropyl-[1-(3-methoxy-propyl)-1H-indol-3-ylmethyl]-carbamoyl}-5-[[2-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-ethyl]-(2-nitro-benzenesulfonyl)-amino]-piperidine-1-carboxylic acid tert-butyl ester (250 mg, 0.3 mmol) in DMF (1 mL) are added thioglycolic acid (104 uL, 1.5 mmol) and DBU (224 uL, 1.5 mmol) at room temperature. After 2.5 h, the reaction mixture is quenched by H2O (20 mL) and extracted with CH2Cl2 (50 mL). The organic phase is successively washed with 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. MS: 658 [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): 3.60 min.
