Ethyl 2-(3-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylate → 2-(3-(4-Fluorobenzyl)-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-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylate, the title compound was obtained in 97% yield: 1H NMR (300 MHz, DMSO-d6) δ 7.84-7.07 (m, 4H), 4.32 (s, 2H), 3.93 (t, J=8.1 Hz, 2H), 3.22 (t, J=8.1 Hz, 2H), 2.46 (s, 3H); MS (ES+) m/z 336.2 (M+1).
