To a CH2Cl2 solution (0.07 M) of 3-{[(3-[(tert-butoxycarbonyl)amino]-2-{4-[2-(2,6-dichloro-4-methylphenoxy)ethoxy]benzyl}propanoyl)(cyclopropyl)amino]methyl}-5-(3-methoxypropyl)phenyl ethylcarbamate from the previous step (1 eq.) was added HCl (4.0 M dioxane solution, 35 eq.). The resulting solution was stirred at RT for 3 h. Following the removal of the volatiles in vacuo, the resulting residue was directly subjected to column chromatography (SiO2, 94:6 (v/v) CH2Cl2:2.0 M NH3 in MeOH) to afford the title compound. MS (ESI+): 686.
