In a manner similar to Example 30, intermediate N-(5-nitropyridin-2-yl)acetamide 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 (DMSO-d6): δ 10.45 (1H, s), 8.07 (1H, d), 7.97 (1H, d), 7.75 (1H, d), 7.33–7.46 (7H, m), 7.29 (1H, m), 7.22 (1H, m), 5.06 (2H, s), 3.79 (3H, s), 2.09 (3H, s); MS(ESI): 488 (MH+).
