1-Methyl-2-methylthioquinolinium p-toluenesulfonate → 3-[3-Benzyl-5-(1-methyl-1H-quinolin-2-ylidene)-4-oxothiazolidin-2-ylideneamino]-4-ethylaminobenzonitrile

Participants

Reaction Steps

In a manner similar to Example 45, intermediate 1-methyl-2-methylthioquinolinium p-toluenesulfonate was condensed with 3-(3-benzyl-4-oxothiazolidin-2-ylideneamino)-4-ethylaminobenzonitrile to afford the title compound. 1H-NMR (CDCl3): δ 7.41–7.58 (4H, m), 7.20–7.38 (9H, m), 6.49 (1H, d), 5.16 (2H, s), 3.79 (3, brs), 3.01 (2H, q), 1.02 (3H, t); MS(ESI): 492 (MH+).
