実験手順
The solution of the compound 9 (258 mg, 0.50 mmol) and ethylenediamine (600 mg, 10 mmol) in methanol (10 mL), water (5 mL) and chloroform (2.5 mL) was refluxed for 24 h. The solvents were then evaporated, the residue was dissolved in 1N potassium hydroxide (15 mL), and the mixture extracted with methylene chloride (4×15 mL). The combined organic phases were washed with water and brine, dried over magnesium sulfate, concentrated under vacuum, and the residue chromatographed on silica gel using chloroform and chloroform-methanol (5%) step-gradient as an eluent to produce pure MCP088 (201 mg, 74%) as orange crystals. 1H NMR (360 MHz, CD3OD): δ 8.04-7.91 (m, 6H), 7.50 (d, J=8.4 Hz, 2H), 6.83 (s, 2H), 4.47 (s, 2H), 3.49 (t, J=6.4 Hz, 2H), 3.26 (septet, J=6.8 Hz, 2H), 2.90 (t, J=6.4 Hz, 2H), 2.55 (t, J=7.6 Hz, 2H), 2.30 (t, J=7.4 Hz, 2H), 1.92 (q, J=7.4 Hz, 2H), 1.19 (d, J=6.8 Hz, 12H). 13C NMR (90.55 MHz, CD3OD): δ 175.13, 168.66, 154.57, 152.02, 148.72, 143.39, 136.55, 135.84, 133.40, 128.42, 128.38, 128.20, 129.90, 123.21, 122.99, 122.65, 120.98, 120.02, 42.66, 42.48, 40.89, 35.54, 35.08, 28.21, 26.83, 22.48. HRMS (m/z): [M+H]+ calcd. for C32H41N5O3 544.3282. found 544.3308.
