Procedure
The product obtained in Step 1 (502 mg, 1.08 mmol) was dissolved in pyridine. Ac2O (0.42 mL, 4.45 mmol) was added, and the reaction mixture was stirred under inert atmosphere at room temperature for 5 h. Concentration in vacuo afforded a yellow oil, which was purified by column chromatography using EtOAc/Et3N (95:5) as eluent to give the title product as a yellow solid: yield 531 mg (97%); MS m/z 509 (M+H)+. Anal. (C26H32N6O5.0.4 H2O) C, H, N.
