The mixture was filtered, concentrated under reduced pressure, and purified by preparative LC-MS (XBridge™ preparative C18 5 μm 30×10 mm OBD™ column, flow rate 60 mL/min., eluting with a gradient of MeCN and water with 0.15% NH4OH) to give the sub-title compound as a colorless gum (4 mg, 41%). LCMS calc. for C32H36F3N6O5 (M+H)+: m/z=641.3. Found: 641.0.
