Procedure

The sulfide of Example 35, (300 mg, 0.95 mmoles), was reacted with 300 mg (1.41 mmoles) NaIO4 in 6 mL MeOH and 3 mL water at 25° C. for 24 h. The reaction mixture was partitioned between 100 mL EtOAc and 25 mL water and the EtOAc extract was washed with water, brine, dried and stripped in vacuo. The residue was purified by silica gel chromatography using 1:1 EtOAc/hexanes as eluent to give 220 mg product, (70% yield); mp 144-146° C. Elemental analysis for C18H25N3O5 : Theory C: 65.22, H: 7.60, N: 12.68, S: 9.67. Found: C: 65.12, H: 7.63, N: 12.48, S: 9.71.
