Ethyl 4-methyl-2-(2-oxo-3-phenylimidazolidin-1-yl)thiazole-5-carboxylate → 2-(3-(Cyclohexylmethyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-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 2-(3-(cyclohexylmethyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylate, the title compound was obtained in 86% yield: 1H NMR (300 MHz, DMSO-d6) δ 4.06-3.82 (m, 2H), 3.52-3.42 (m, 2H), 298 (d, J=6.9 Hz, 2H), 2.52 (s, 3H), 1.73-1.52 (m, 6H), 1.27-1.08 (m, 3H), 0.90-0.72 (m, 2H); MS (ES+) m/z 324.2 (M+1).
