N-(2-(Benzyloxy)-5-{(1R)-2-iodo-1-[(triethylsilyl)oxy]ethyl}phenyl)methanesulfonamide (E. J. Corey and J. O. Link, J. Org. Chem., 1991, 56, 422 and WO 9737646) (1.0 g, 1.93 mmol) was refluxed in anhydrous tetrahydrofuran (30 mL) with 4-[4-(2-aminoethyl)anilino]-N-octyl-1-piperidinecarboxamide (1.48 g, 3.98 mmol) and N,N-diisopropylethylamine (0.69 mL). The reaction was stirred at reflux for 7 days. The solvent was removed in vacuo and the residue was purified by flash chromatography on silica gel Merck-60 (eluant: 20:1 chloroform-methanol containing 2% triethylamine) to furnish the title compound (0.92 g, 1.14 mmol).
