1-Methyl-2-methylthioquinolinium p-toluenesulfonate → 2-(5-acetyl-2-ethylaminophenylimino)-3-benzyl-5-(1-methyl-1H-quinolin-2-ylidene)thiazolidin-4-one

Participants

Reaction Steps

In a manner similar to Example 102, 1-methyl-2-methylthioquinolinium p-toluenesulfonate was condensed with 2-(5-acetyl-2-ethylaminophenylimino)-3-benzylthiazolidin-4-one to afford the title compound. 1H-NMR (CDCl3): δ 7.66–7.71 (2H, m), 7.43–7.56 (4H, m), 7.20–7.38 (7H, m), 6.53 (1H, d), 5.20 (2H, s), 3.78 (3H, br s), 3.07 (2H, q), 2.51 (3H, s), 1.06 (3H, t); MS(ESI): 509 (MH+).
