Procedure

The product of Example 59 (200 mg, 0.47 mmol) was dissolved in THF (4 ml) and a solution of ethanolamine (115 mg, 1.87 mmol) in THF (1 mL) was added. The mixture was stirred under Ar at 23° for 18 h. The solvents were removed in vacuo, and the residue was partitioned between EtOAc and H2O. The organic phase was washed with H2O, satd aq NaCl, dried over anhyd Na2SO4, filtered and evaporated to give the crude product. Flash chromatography eluted with 0-15% EtOAc/CH2Cl2 gave the title compound as a light-yellow amorphous solid. mp 120-124°, LC MS m/z=409 (MH+) Retention time=1.84 min.
