Versuchsvorschrift
This compound was prepared by the method described in General Procedure 3 using 2-chloro-4-[3-(4-methyl-piperazin-1-yl)-propoxy]-benzaldehyde (200 mg, 0.68 mmol, 1.0 equiv), 4-trifluoromethoxy-benzene-1,2-diamine (119 mg, 0.62 mmol, 0.92 equiv) and Na2S2O5 (167 mg, 0.88 mmol, 1.3 equiv). Purification by Method 2 afforded 72 mg (23%) of the title compound. MS (electrospray): mass calculated for C22H24ClF3N4O2, 468.15; m/z found, 469.4 [M+H]+. 1H NMR (400 MHz, CD3OD): 7.82 (d, J=8.7 Hz, 1H), 7.69 (d, J=8.8 Hz, 1H), 7.55 (s, 1H), 7.23 (d, J=8.5 Hz, 1H), 7.21 (d, J=1.6 Hz, 1H), 7.1 (dd, J=8.6, 2.2 Hz, 1H), 4.17 (t, J=5.7 Hz, 2H), 2.88-2.38 (m, 10H), 2.32 (s, 3H), 2.10-1.95 (m, 2H).
