Procedure

The product of Example 48 (200 mg, 0.45 mmol) and (S)-2-amino-1-propanol (75 mg, 1 mmol) were dissolved in THF (10 ml) and stirred under Ar at 230 for 10 days. 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 an off-white amorphous solid. mp 96-101°, LC MS m/z=441 (MH+). Retention time=2.04 min.
