In a manner similar to Example 30, intermediate 4-ethylamino-3-nitrobenzoic acid tert-butyl ester 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 7.69 (1H, dd), 7.61 (1H, d), 7.52 (1H, dd), 7.45–7.49 (2H, m), 7.27–7.37 (4H, m), 7.18 (1H, m), 7.06 (1H, d), 6.51 (1H, d), 5.19 (2H, s), 4.11 (1H, br t), 3.79 (3H, s), 3.04 (2H, m), 1.57 (9H, s), 1.04 (3H, t); MS(ESI): 573 (MH+).
