Procedure
In a manner similar to Example 30, intermediate 4-ethylamino-3-nitropyridine was hydrogenated and then condensed with 3-benzyl-5-(3-methyl-3H-benzothiazol-2-ylidene)-2-methylthio-4-oxo-2-thiazolium p-toluenesulfonate to afford the title compound. 1H-NMR (CDCl3): δ 8.04–8.09 (2H, m), 7.53 (1H, d), 7.44–7.48 (2H, m), 7.27–7.38 (4H, m), 7.19 (1H, m), 7.07 (1H, d), 6.42 (1H, d), 5.19 (2H, s), 4.12 (1H, br t), 3.79 (3H, s), 3.02 (2H, m), 1.05 (3H, t); MS(ESI): 474 (MH+).
