Versuchsvorschrift

The acid from Example 33F was dissolved in DMF (6.0 mL). N,N-diethyl-benzene-1,4-diamine sulfate (786 mg, 3.0 mmol), Et3N (1.0 g, 10 mmol), and TBTU (963 mg, 3.0 mmol) were added and the resulting mixture was stirred overnight and purified by column chromatography to provide the titled compound (680 mg, 40% over two steps). 1H NMR (400 MHz, DMSO-D6) δ 9.07 (s, 1H), 7.30 (d, J=8.4 Hz, 2H), 7.07 (t, J=7.6 Hz, 1H), 6.77 (d, J=8.0 Hz, 1H), 6.68 (d, J=7.2 Hz, 1H), 6.60 (d, J=8.8 Hz, 2H), 3.78 (s, 3H), 3.76 (m, 2H), 3.27 (q, J=6.8 Hz, 4H), 3.12 (d, J=17.6 Hz, 1H), 2.87 (d, J=16.0 Hz, 1H), 2.85 (s, 3H), 2.64 (m, 2H), 2.32 (m, 1H), 2.19 (m, 1H), 1.80 (m, 1H), 1.05 (t, J=6.8 Hz, 6H), and 0.85 (d, J=6.4 Hz, 6H). MS (ESI) positive ion 482 (M+H)+.
