Procedure

To a cold (0° C.), stirred solution of COMPOUND 249 (66 mg, 0.21 mmol) in CH2Cl2 (2 mL) was added phenyl isocyanate (30 μL, 0.28 mmol). After 15 minutes, the cooling bath was removed and the reaction mixture was warmed to room temperature. After an additional 45 minutes, the mixture was concentrated under reduced pressure. Purification of the crude material by radial chromatography on silica gel (1 mm plate, 25:1:1 CH2Cl2-MeOH—NH4OH) provided 84 mg (84%) of COMPOUND 270 as a white solid. 1H NMR (CDCl3) δ 1.62-1.78 (m, 2H), 1.95-1.99 (m, 2H), 2.09 (s, 6H), 2.68-2.79 (m, 3H), 3.83 (s, 4H), 4.14 (d, 2H, J=13.5 Hz), 6.39 (br s, 1H), 6.99-7.12 (m, 3H), 7.25-7.39 (m, 6H), 8.34 (d, 2H, J=3.6 Hz); 13C NMR (CDCl3) δ 18.39, 27.45, 44.86, 54.98, 57.83, 120.41, 122.86, 123.17, 129.13, 133.86, 138.50, 139.80, 146.23, 155.40, 157.50; ES-MS m/z 430 (M+H). Anal. Calcd. For C26H31N5O.0.5CH2Cl2: C, 67.43; H, 6.83; N, 14.84. Found: C, 67.77; H, 6.99; N, 14.90.
