The product from Example 1D (50 mg, 0.22 mmol) in DMF (1 mL) was treated with 1-fluoro-2-isocyanato-4-methyl-benzene (0.03 mL, 0.22 mmol) and stirred for 16 hours. The crude product was directly purified via preparative HPLC on an Agilent Zorbax Stablebond C-18 (7 micron particle size) preparative column using a solvent gradient of 30% to 100% acetonitrile in 0.1% aqueous TFA at a flow rate of 15 mL/minute. The product was further purified via silica gel chromatography eluting with 5% methanol/CH2Cl2 to provide 4 mg ofthe title compound.
