Procedure

A mixture of N-(2-amino-ethyl)-N-[4-(tert-butyl-dimethyl-silanyloxy)-1-(4-chloro-benzoyl)-pyrrolidin-3-yl]-2-chloro-acetamide and N-(2-amino-ethyl)-2-chloro-N-[1-(4-chloro-benzoyl)-4-hydroxy-pyrrolidin-3-yl]-acetamide (200 mg) was dissolved in 2 mL of DMF. Then K2CO3 (117 mg, 0.84 mmol) and Cat. KI were added. The mixture was stirred at 90° C. for overnight. EtOAc (5 mL) was added. The organic phase was washed with Sat. NaHCO3, dried over Na2SO4, and concentrated. The residue was purified by column chromatography (Ethyl acetate:Methanol:Et3N:3:1:0.04) to give the desired product (50 mg, 37% yield) as a colorless oil. MS (ESI), M/Z, 324 (M+1). Retention time: 1.13 min (FA-polar).
