Versuchsvorschrift
Following the procedure described in Example 22, but substituting carboxylic acid 50h for carboxylic acid 50g and 5-amino-1,3,4thiadiazole-2-thiol for 1,2-phenylenediamine respectively, the title compound 79 was obtained in 34% yield. 1H NMR (300 MHz, 20% CD3OD in CDCl3): δ 7.91 (d, J=8.4 Hz, 2H), 7.58(d, J=8.4 Hz, 2H), 7.52 (m, 2H), 7.38-7.26 (m, 3H), 2.90 (t, J=7.2 Hz, 2H), 2.30 (t, J=7.2 Hz, 2H), 1.62 (m, 4H), 1.30 (m, 4H).
