Reaction Steps

tert-Butyl (3R,5S)-3-cyano-5-{{{1-(4-methoxybutyl)-1H-benzimidazol-2-yl}carbonyl}(2-methylpropyl)amino}piperidine-1-carboxylate (320 mg) was dissolved in tetrahydrofuran (20 ml), azido(trimethyl)silane (1.5 ml) and dibutyl(oxo)stannane (100 mg) were added, and the mixture was heated under reflux with stirring for 43 hr. The reaction mixture was concentrated under reduced pressure, and the residue was subjected to silica gel chromatography, and a fraction eluted with ethyl acetate-ethyl acetate-methanol (8:2) was concentrated under reduced pressure to give the object product (304 mg).
