Reaction Steps

To a solution tert-butyl (3R,4S)-3-({cyclopropyl[3-{[(1R,2R)-2-(ethoxy-carbonyl)cyclopropyl]methoxy}-5-(3-methoxypropyl)benzyl]amino}carbonyl)-4-{4-[2-(2,6-dichloro-4-methylphenoxy)ethoxy]phenyl}piperidine-1-carboxylate (1 eq.) from the previous step in DCM (0.05 M) was added 4 M HCl in dioxane (10 eq.) and stirred at rt for 5 h. The reaction was concentrated in vacuo. The crude product was purified by flash column chromatography (SiO2, 5% [2 M NH3 in MeOH] in DCM) to afford the title compound as a colorless oil.
