4-Fluorobenzyl bromide → Ethyl 2-(3-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylate

Participants

Reaction Steps

Following the procedure as described in Example 13, making variations as required to replace 4-(trifluoromethyl)benzyl bromide with 1-(bromomethyl)-4-fluorobenzene to react with ethyl 4-methyl-2-(2-oxoimidazolidin-1-yl)thiazole-5-carboxylate, the title compound was obtained as a colorless solid in 69% yield: 1H NMR (300 MHz, CDCl3) δ 7.31-7.28 (m, 2H), 7.07-7.02 (m, 2H), 4.47 (s, 2H), 4.29 (q, J=6.0 Hz, 2H), 4.08 (t, J=9.0 Hz, 2H), 3.46 (t, J=9.0 Hz, 2H), 2.62 (s, 3H), 1.34 (t, J=6.0 Hz, 3H); MS (ES+) m/z 364.1.0 (M+1).
