実験手順
To a solution of (3R*,4R*)-3-({isopropyl-[4-methoxy-3-(3-methoxy-propoxy)-benzoyl]-amino}-methyl)-4-methylaminomethyl-pyrrolidine-1-carboxylic acid tert-butyl ester (134 mg, 0.264 mmol) in CH2Cl2 (2 mL), cyclopropanecarbonyl chloride (29 μL, 0.317 mmol) and triethylamine (44 μL, 0.317 mmol) are added under N2 atmosphere. The mixture is stirred overnight at RT, diluted with CH2Cl2 and poured into an aqueous saturated solution of NaHCO3. The organic layer is separated, and the aqueous one is extracted twice with CH2Cl2. The combined organic extracts are dried over Na2SO4, filtered and concentrated. The crude product is used in the next step without purification. TLC, Rf (CH2Cl2/MeOH 95:5)=0.2. MS (LC-MS): 476.1 [M+H-Boc]+. 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): 5.42 min.
