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-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid to react with 4-fluorobenzylamine in place of benzylamine, the title compound was obtained as a white powder in 38% yield: mp 177-178° C.; NMR (300 MHz, CDCl3) δ 729-721 (m, 4H), 7.04-6.96 (m, 4H), 5.98 (s, 1H), 4.50 (d, J=5.7 Hz, 2H), 4.41 (s, 2H), 4.03 (t, J=8.1 Hz, 2H), 3.42 (t, J=8.1 Hz, 2H), 2.58 (s, 3H); 13C NMR (75 MHz, CDCl3) δ 164.1, 162.4, 160.8, 155.3, 153.2, 133.8, 131.3, 129.9, 129.5, 117.2, 115.7, 115.4, 47.2, 43.2, 42.0, 41.6, 17.2; MS (ES+) m/z 443.2 (M+1).
