Using General Procedure B, to a solution of COMPOUND 249 (0.1331 g, 0.43 mmol) in CH3CN (5 mL) was added Ac2O (0.05 mL, 0.51 mmol), Et3N (0.09 mL, 0.65 mmol), and KI (0.0116 g, 0.04 mmol). Purification of the crude material by column chromatography on silica gel (50:1:1 CH2Cl2-MeOH—NH4OH) provided 83.5 mg (53%) of COMPOUND 251 as a white solid. 1H NMR (CDCl3) δ 1.53-1.69 (m, 2H), 1.78-1.85 (m, 2H), 2.08 (s, 9H), 2.35 (t, 1H, J=13.0 Hz), 2.72 (t, 1H, J=12.0 Hz), 2.91 (t, 1H, J=12.0 Hz), 3.73-3.90 (m, 5H), 4.69 (d, 1H, J=24.0 Hz), 7.06-7.11 (m, 2H), 7.36 (d, 2H, J=9.0 Hz), 8.35 (d, 2H, J=3.0 Hz). 13C NMR (CDCl3) δ 18.35, 21.86, 27.09, 28.19, 42.05, 46.79, 54.99, 57.78, 122.82, 133.77, 138.43, 146.31, 157.49, 169.14. ES-MS m/z 353 (M+H). Anal. Calcd. for C21H28N4O.H2O: C, 69.43; H, 8.10; N, 15.42. Found: C, 69.52; H, 7.82; N, 15.28.
