Procedure

To a solution of 2-{(RS)-2-(tert-Butyl-dimethyl-silanyloxy)-1-[(3RS,4SR)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-ethoxy}-5-chloro-pyridine (8A-1) (220 mg) in DMF (12 mL) at −20° C. were added Hunig base (0.132 mL, 0.78 mmol) and then HATU (202 mg). The mixture was diluted with ethyl acetate and washed with aq.ammonium chloride solution three times and aq. sodium bicarbonate solution. The separated organic phase was dried over sodium sulfate and concentrated in vaccuo after filtration. The residue was purified by TLC (SiO2, MeOH/DCM, 1:20) yielded 24 mg (40%) of the title compound as a light yellow oil. ES-MS m/e: 623.1 M+H+).
