Procedure

To a stirred solution of ({5-[(S)-3-(carbamoyldiphenylmethyl)pyrrolidin-1-yl]pentylcarbamoyl}methyl)methylcarbamic acid tert-butyl ester (23.47 g, 43.7 mmol) in DCM (60 mL) was added 4 N HCl in dioxane (100 mL). The reaction mixture was stirred at room temperature for 2 hours and then concentrated to dryness. The residue was dissolved in water (100 mL) and this solution was washed with DCM (4×60 mL). The aqueous phase was then made basic with 20% aqueous potassium carbonate and extracted with DCM (4×60 mL). The combined organic phase was dried over magnesium sulfate, filtered and concentrated. The residue was then dissolved in water (50 mL) containing TFA (2.5 eq) and purified by HPLC to obtain 17.5 g of the title compound as a bis(trifluoroacetate) salt. MS m/z [M+H+] calc'd for C26H36N4O2 437.3; found 437.5.
