実験手順

To a solution of (3R*,4R*)-3-[(cyclopropanecarbonyl-methyl-amino)-methyl]-4-({isopropyl-[4-methoxy-3-(3-methoxy-propoxy)-benzoyl]-amino}-methyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (154 mg, 0.267 mmol) in 3 mL CH2Cl2, TFA (309 μL, 4.01 mmol) is added. The mixture is stirred 4 h at RT, and poured into a saturated solution of NaHCO3. The layers are separated, and the aqueous one is back-extracted twice with CH2Cl2. The combined organic extracts are dried over Na2SO4, filtered and concentrated. The crude material is purified by flash chromatography on Isolute SPE Flash NH2 column (eluent: CH2Cl2/MeOH 100:0 to 95:5) to give the title product. TLC, Rf (SiO2—NH2, CH2Cl2/MeOH 95:5)=0.1. MS (LC-MS): 476.1 [M+H]+; tR (HPLC, Nucleosil C18 column, 10-100% CH3CN/H2O/5 min, 100% CH3CN/3 min, CH3CN and H2O containing 0.1% TFA, flow: 1.5 mL/min): 4.10 min.
