实验过程
The title compound was prepared from the HATU-mediated coupling of 4,5-dichloro-2-(quinoxaline-5-sulfonylamino)-benzoic acid (EXAMPLE 5, Step D) and morpholine and purified as described in EXAMPLE 1, Step K. MS (ESI): mass calculated for C19H16Cl2N4O4S, 466.0; m/z found, 465/467 [M−H]−. HPLC (reverse phase): RT=8.84 min. 1H NMR (500 MHz, CDCl3, rotameric broadening): 9.06 (d, J=1.8 Hz, 1H), 9.03 (d, J=1.8 Hz, 1H), 8.51 (dd, J=7.0, 1.5 Hz, 1H), 8.38 (dd, J=8.4, 1.4 Hz, 1H), 8.08 (d, J=1.5 Hz, 1H), 7.91 (dd, J=8.4, 7.4 Hz, 1H), 7.70 (s, 1H), 7.14 (s, 1H), 4.35-4.10 (br m, 4H), 3.65-3.48 (br m, 4H).
