实验过程

From (3S,4R)-3-(tert-butyl-dimethyl-silanyloxymethyl)-4-({[4-ethyl-3-(3-methoxy-propoxy)-benzoyl]-isopropyl-amino}-methyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (13.1 g, 21.6 mmol) and TBAF (17 g, 54 mmol), and purification by flash chromatography on silica gel (CH2Cl2/MeOH 95:5) to give the title compound as yellow oil. TLC, Rf (AcOEt)=0.4,MS (LC-MS): 437.3 [M+H-tBu]+; tR (HPLC, Macherey-Nagel 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): 6.74 min.
