Vorschrift

To a 50 mL round-bottomed flask containing (E)-methyl 2-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)benzylidene)hydrazinecarbodithioate (250 mg, 0.571 mmol) in DMF (3 mL) was added N1,N1-dimethylbenzene-1,3-diamine (195 mg, 1.43 mmol). The contents were heated at 150° C. with stirring for 5 h before the solution was allowed to cool overnight. The mixture was filtered, and the filtrate purified via RP-HPLC to afford the desired material (235 mg, 78%) as an off-white solid: mp 192-194° C.; 1H NMR (400 MHz, DMSO-d6) δ 11.82 (s, 1H), 10.04 (s, 1H), 9.41 (s, 1H), 8.19 (s, 1H), 8.16-7.99 (m, 6H), 7.61 (d, J=8.3 Hz, 2H), 7.16 (t, J=7.2 Hz, 1H), 7.01 (m, 1H), 6.87 (m, 1H), 6.58 (m, 1H), 2.88 (s, 6H); ESIMS m/z 526 ([M+H]+).
