Reaction Steps

To a solution of COMPOUND 249 (0.1189 g, 0.38 mmol) in CH3CN (4 mL) was added Et3N (0.08 mL, 0.57 mmol), KI (0.0063 g, 0.04 mmol), and 2-bromoethanol (0.03 mL, 0.46 mmol), and stirred at room temperature for 23 hours. Saturated NaHCO3 (10 mL) was added and extracted with CH2Cl2 (3×30 mL), and the combined organic extracts were dried (Na2SO4), filtered, and concentrated. Purification of the crude material by column chromatography on silica gel (25:1:1 CH2Cl2-MeOH—NH4OH) provided 0.0946 g (66%) of COMPOUND 339 as a pale yellow oil. 1H NMR (CDCl3) δ 1.71-1.98 (m, 6H), 2.09 (s, 6H), 2.46 (t, 3H, J=5.1 Hz), 2.94 (d, 3H, J=10.8 Hz), 3.56 (t, 2H, J=5.1 Hz), 3.82 (s, 4H), 7.04-7.08 (m, 2H), 7.34 (d, 2H, J=7.5 Hz), 8.33 (d, 2H, J=4.2 Hz). 13C NMR (CDCl3) δ 18.35, 27.34, 53.93, 55.13, 57.82, 58.52, 59.74, 122.63, 133.76, 138.29, 146.15, 157.80. ES-MS m/z 355.5 (M+H). Anal. Calcd. for C21H30N4O.0.3CH2Cl2: C, 67.33; H, 8.12; N, 14.74. Found: C, 67.46; H, 8.43; N, 14.93.
