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 4-fluorobenzylamine in place of benzylamine, the title compound was obtained as a white powder in 34% yield: mp 122-123° C.: 1H NMR (300 MHz, CDCl3) δ 7.27-7.23 (m, 2H), 7.00-6.94 (m, 2H), 5.98 (s, 1H), 4.48 (d, J=5.7 Hz, 2H), 4.05 (t, J=7.8 Hz, 2H), 3.56 (t, J=8.7 Hz, 2H), 3.35 (t, J=7.8 Hz, 2H), 2.57 (s, 3H), 1.47-1.40 (m, 2H), 0.67-0.56 (m, 1H), 0.46-0.37 (m, 2H), 0.06-0.01 (m, 2H); 13C NMR (75 MHz, CDCl3) δ 163.8, 162.5, 157.4, 155.3, 153.2, 133.9, 129.5, 116.8, 115.6, 44.0, 43.2, 42.7, 42.0, 32.4, 17.2, 8.4, 4.3; MS (ES+) m/z 403.2 (M+1).
