Procedure

from (3S*,4R*)-3-formyl-4-({isopropyl-[4-methoxy-3-(3-methoxy-propoxy)-benzoyl]-amino}-methyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (0.75 g, 1.52 mmol), cyclopropanemethylamine (0.652 mL, 7.61 mmol) and NaBH4 (0.115 g, 3.04 mmol) and purification by flash chromatography on silica gel (CH2Cl2/MeOH 96:4, then CH2Cl2/MeOH (10% NH3 conc.) gradient from 9:1 to 8:2) to give the title compound as colorless oil. MS: 548.4 [M+H]+. tR (HPLC, Nucleosil C18HD column, 5-100% CH3CN/H2O/6 min, 100% CH3CN/2 min, CH3CN and H2O containing 0.1% TFA, flow: 1 mL/min): 4.66 min.
