Reaction Steps

To a solution of 1,1-dimethylethyl 4-{[3-({[(3′-{[(3S)-3,4-dimethyl-1-piperazinyl]methyl}-6-fluoro-3-biphenylyl)methyl]amino}carbonyl)phenyl]methyl)-1-piperidinecarboxylate (250 mg, 0.40 mmol) in 5 mL of 1,4-dioxane was added 4M HCl in 1,4-diozane (5 mL). The mixture was stirred at room temperature for 30 min. After removal of the solvent, the crude was purified by Gilson reverse phase HPLC, eluting with acetonitrile/water/0.1% TFA (10/90 to 70/30, v/v, over 12 min), to give the title compound (200 mg, 95%). LC/MS: m/z, 529 (M+H), 1.27 min.
