Ethyl 4-methyl-2-(2-oxo-3-phenylimidazolidin-1-yl)thiazole-5-carboxylate → 4-Methyl-2-(2-oxo-3-(3-phenylpropyl)imidazolidin-1-yl)thiazole-5-carboxylic acid

Participants

Reaction Steps

Following the procedure as described in Example 6, making variations as required to replace ethyl 4-methyl-2-(2-oxo-3-phenylimidazolidin-1-yl)thiazole-5-carboxylate with ethyl 4-methyl-2-(2-oxo-3-(3-phenylpropyl)imidazolidin-1-yl)thiazole-5-carboxylate, the title compound was obtained in 99% yield: mp 218-221° C.; 1H NMR (300 MHz, DMSO-d6) δ 7.25-7.10 (m, 5H), 3.94-3.89 (m, 2H), 3.53-3.48 (m, 2H), 3.22 (t, J=6.9 Hz, 2H), 2.55 (t, J=7.5 Hz, 2H), 2.46 (s, 3H), 1.83-1.73 (m, 2H); MS (ES+) m/z 346.2 (M+1).
