Versuchsvorschrift

A solution of N-{2-[(3S)-4-{[tert-butyl(diphenyl)silyl]oxy}-3-{[(4-nitrophenyl)sulfonyl]amino}butyl]phenyl}-Nα-(methoxycarbonyl)-β-phenyl-L-phenylalaninamide (9, 160 mg, 0.181 mmol), Ph3P (149 mg, 0.568 mmol) and isoamyl alcohol (89 mg, 1.01 mmol) (or any other suitable alcohol) in THF (1.5 ml) stirred at external temperature of 0° C. under N2 atmosphere, was treated with neat DIAD (150 μL, 0.771 mmol) and the mixture stirred at the same temperature for 30 min and then at room temperature in the dark for 16 h, concentrated and purified in a cromatographic cartridge of silicagel (24 g) eluted with 10% to 40% EtOAc in hexane, to get 143 mg (83%) of the title compound as white foam MS: m/z=955.3 (MH+).
