Procedure
To a stirred solution of (2S,3S)-2-amino-3-(4-fluorophenyl)-3-(3,5-difluorophenyl)-N-(5-fluoro-4-(2-((2R,5R)-4-(tert-butyloxycarbonyl)-5-(2,2,2-trifluoroethylaminocarbonyloxymethyl)morpholine-2-yl)ethyl)pyridin-3-yl)propanamide (Example 90, step 5) (64 mg, 0.084 mmol) in 1 mL of CH2Cl2 was added triethylamine (0.047 mL, 0.34 mmol) and methyl chloroformate (0.013 mL, 0.17 mmol). The mixture was stirred at ambient temperature for 1 h, then diluted with CH2Cl2 and washed with aqueous NaHCO3 and brine. The organic phase was dried (MgSO4), filtered, and the solvents were removed in vacuo. The residue was chromatographed on a 12 g SiO2 column using a gradient elution of 0-100% EtOc in hexanes. Fractions containing product were combined and the solvents were removed in vacuo to give a gum. LC MS: RT=1.38 min, M+H=816 (2 min gradient)
