Versuchsvorschrift

To a solution of compound obtained in Example 259 (100 mg, 0.20 mmol) in 10% Et3N/pyridine (10 mL) at 0° C. was bubbled dry H2S gas to saturation. The mixture was stirred at ambient temperatures overnight, and the conversion was complete. The solvent was removed to dryness, and the residue was suspended in anhydrous acetone. (10 mL), followed by addition of MeI (1 mL). The reaction mixture was refluxed for 1 hour. The solvent was removed by rotary evaporation. To the residue was added anhydrous MeOH (10 mL) and N-methylethylenediamine (1 mL). The resulting mixture was refluxed for 1 hour, concentrated and subjected to RP-HPLC purification to give the title compound. MS found for C25H24BrN5O4 (M+H)+: 538.1, 540.1.
