PROCEDURE
实验过程
The amine from above (131 mg, 0.28 mmol), and imidazole-1-carboxylic acid (1H-imidazol-2-yl)-amide (168 mg, 0.56 mmol) were combined in DMF (4.0 mL) and treated with DIPEA (0.29 mL, 1.7 mmol). The solution was stirred at 75° C. for 2 hours and then concentrated under reduced pressure. This afforded, after column chromatography with silica gel (25:1:0.1 CH2Cl2:MeOH:NH4OH), COMPOUND 307 (72 mg, 45%). 1H NMR (CDCl3): δ 1.30 (q, 2H, J=11.1 Hz), 1.59 (s, 6H), 1.66 (d, 2H, J=12.3 Hz), 2.26 (s, 3H), 2.61 (br t, 3H, J=11.7 Hz), 3.35 (s, 2H), 3.65 (s, 2H), 4.14 (d, 2H, J=13.2 Hz), 6.68 (s, 2H), 6.86 (m, 4H), 7.19 (br, 2H), 7.37 (s, 1H), 7.82 (d, 1H, J=7.5 Hz), 8.20 (s, 1H), 8.48 (br d, 1H). 13C NMR (CDCl3) δ 18.40, 18.81, 28.08 (2C), 31.12 (2C), 42.14, 44.20 (2C), 54.06, 54.67, 58.01, 115.13 (d, 2C, J=84 Hz), 121.44, 127.07 (d, 2C, J=30 Hz), 130.07, 133.81, 134.84, 137.31, 142.96, 144.59 (2C), 145.07, 145.36, 146.61 (2C), 155.31, 155.96, 157.96, 161.91 (d, 1C, 975 Hz). ES-MS m/z 577 (M+H). Anal. Calcd. for C31H35N7OClF.0.2CH2Cl2O.0.2H2O: C, 62.46; H, 6.02; N, 16.32; Cl, 8.85; F, 3.16. Found: C, 62.60; H, 6.02; N, 16.09; Cl, 8.79; F, 2.94.
