실험 절차

In a manner similar to Example 1, intermediate 3-benzyl-1-methyl-5-(3-methyl-3H-benzothiazol-2-ylidene)-2-thioxoimidazolidin-4-one was alkylated with methyl p-toluenesulfonate and condensed with 3′-amino-4′-ethylaminoacetophenone to yield the title compound. 1H-NMR (CDCl3): δ 8.11 (1H, d), 7.84 (1H, dd), 7.51 (1H, dd), 7.31 (1H, m), 7.16 (1H, m), 6.95–7.12 (7H, m), 6.08 (1H, br t), 4.46 (2H, hs m), 3.99 (2H, m), 3.78 (3H, s), 3.50 (3H, s), 2.65 (3H, s), 1.06 (3H, t); MS(ESI): 512 (MH+).
