Procedure
To a solution of the title compound of Example 16b (440 mg, 0.81 mmol) in tetrahydrofuran (9 mL) and methanol (3 mL) was added NH2OH (50% aqueous solution, 0.74 mL, 12 mmol). After stirring for 20 hours at room temperature, the solution was concentrated. Purification by flash chromatography (5:95 MeOH/CHCl3) yielded the title compound as a white solid (80 mg, 18%): Anal. Calcd. for C25H25N3O7S2.0.25 H2O: C, 54.78; H, 4.69; N, 7.67; S, 11.70. Found: C, 54.78; H, 4.72; N, 7.46; S, 11.53.
