Versuchsvorschrift

To a suspension of biphenyl-2-ylcarbamic acid 1-[2-(4-{[(R)-2-(tert-butyldimethylsilanyloxy)-2-(3-formylamino-4-hydroxyphenyl)ethylamino]methyl}-2,5-dimethylphenylcarbamoyl)-ethyl]piperidin-4-yl ester (238 mg, 0.30 mmol) in dichloromethane (3.0 mL) was added triethylamine trihydrofluoride (147 μL, 0.90 mmol). This mixture was stirred at room temperature overnight and then the mixture was concentrated under reduced pressure. The residue was purified by prep-RP-HPLC (gradient: 2 to 50% acetonitrile in water with 0.05% TFA). The appropriate fractions were collected and combined and lyophilized to give biphenyl-2-ylcarbamic acid 1-[2-(4-{[(R)-2-(3-formylamino-4-hydroxyphenyl)-2-hydroxyethylamino]methyl}-2,5-dimethylphenylcarbamoyl)ethyl]piperidin-4-yl ester as the ditrifluoroacetate salt (50 mg, 97% purity). LPLC (2-90) Rt=2.76; [M+H+] found 680.8.
