Reaction Steps
The title compound is prepared in a similar manner as described for Example 9/reaction step I, from (3S*,4R*)-3-hydroxymethyl-4-({isopropyl-[4-methoxy-3-(3-methoxy-propoxy)-benzoyl]-amino}-methyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (4.9 g, 9.95 mmol) and Dess-Martin periodinane (4.22 g, 9.95 mmol) in CH2Cl2 (30 mL), slowly wet CH2Cl2 (0.20 mL of water in 30 mL of CH2Cl2) as colorless oil. MS: 437.2 [M+H-BOC]+. tR (HPLC, Nucleosil C18 column, 5-100% CH3CN/H2O/6 min, 100% CH3CN/1.5 min, CH3CN and H2O containing 0.1% TFA, flow: 1.5 ml/min): 4.99 min.
