Participants

Reaction Steps

Following the procedure as describe in Example 9, making variations as required to replace 2-(3-benzyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid with 2-(3-(2-cyclopropylethyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid to react with benzylamine, the title compound was obtained as a white powder in 15% yield: mp 137-138° C.: 1H NMR (300 MHz, CDCl3) δ 7.36-7.25 (m, 5H), 5.88 (s, 1H), 4.54 (d, J=5.7 Hz, 2H), 4.09 (t, J=7.8 Hz, 2H), 3.58 (t, J=8.7 Hz, 2H), 3.37 (t, J=7.8 Hz, 2H), 2.60 (s, 3H), 1.46 (m, 2H), 0.70-0.58 (m, 1H), 0.46-0.37 (m, 2H), 0.13-0.03 (m, 2H); 13C NMR (75 MHz, CDCl3) δ 162.4, 155.3, 153.0, 137.9, 128.7, 127.8, 127.6, 44.8, 44.0, 42.5, 42.0, 32.4, 17.1, 8.4, 4.3: MS (ES+) m/z 385.2 (M+1).
