Procedure

(2S,4S)-1-Boc-4-azido-2-[(4-methylpiperazin-1-yl)carbonyl]pyrrolidine (11.67 g, 34.48 mmol) obtained in Step B was dissolved in THF (30 mL). Trimethyl phosphine (3.40 mL, 38.37 mmol) was added dropwise thereto at 0-5° C. The reaction solution was stirred for 2 hours at room temperature, concentrated in vacuo and basified with saturated NaHCO3 aqueous solution. The solution was extracted with EtOAc two times and concentrated in vacuo to give the title compound in oil form (10.61 g, 98.5%).
