Reaction Steps

To a solution of [(3S*,4S*)-1-benzyl-4-(isopropylamino-methyl)-pyrrolidin-3-ylmethyl]-isopropyl-carbamic acid tert-butyl ester (0.32 g, 0.55 mmol), 4-methoxy-3-(3-methoxy-propoxy)-benzoic acid (0.23 g, 0.96 mmol), DMAP (0.12 g, 0.96 mmol), and triethyl-amine (0.56 mL, 0.96 mmol) in DMF (10 mL), is added EDCl-HCl (0.19 g, 0.96 mmol) at 0° C. The reaction mixture is stirred overnight at room temperature. Water and Et2O are added, the layers are separated and the aqueous one is extracted twice with Et2O. The combined organic extracts are dried (MgSO4), and the solvent is removed in vacuo. The crude product is purified by flash chromatography on silica gel (eluent: CH2Cl2/MeOH 90:10) to give the title product. TLC, Rf (CH2Cl2/MeOH 9:1)=0.72. MS (LC-MS): 626.4 [M+H]+; tR (HPLC, C18 column, 10-100% CH3CN/H2O/5 min, 100% CH3CN/2.5 min, CH3CN and H2O containing 0.1% TFA, flow: 1.5 mL/min): 6.28 min.
