Procedure

To a solution of the compound from Example 100 (60 mg) in dry THF (2 mL) was added DIEA (0.044 mL), methylchloroformate (0.02 mL) and DMAP (catalytic amount). The reaction mixture was heated at 80° C. for 3 days during which more methylchloroformate (0.1 mL) was added after 24 hours and 48 hours. Water (10 mL) and EtOAc (10 mL) were added and the mixture shaken. The aqueous phase was separated and extracted with EtOAc. The combined organics were dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by chromatography (silica gel; EtOAc/hexanes; chromatotron) to give the titled compound (37 mg). MS (m/z) 529 (MH+); Mp. 81 CC.
