Following the procedure as described in Example 26, making variations as required to replace 2-(3-(cyclopropylmethyl)-2-oxoimidazolidin-1-yl)thiazole-5-carboxylic acid with 2-(3-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)-4-(trifluoromethyl)thiazole-5-carboxylic acid to react with pyridin-3-ylmethanamine, the title compound was obtained as a colorless solid in 37% yield: mp 161-162° C. (ethyl acetate/hexanes); 1H NMR (300 MHz, CDCl3) δ 8.56-8.52 (m, 2H), 7.69-7.66 (m, 1H), 7.31-7.22 (m, 3H), 7.05-7.00 (m, 2H), 6.55-6.47 (m, 1H), 4.61 (d, J=5.8 Hz, 2H), 4.43 (s, 2H), 4.09-4.03 (m, 2H), 3.48-3.43 (m, 2H); 13C NMR (75 MHz, CDCl3) δ 164.2, 160.9, 159.5, 159.0, 155.2, 149.2, 135.6, 132.9, 131.0, 130.1, 127.2, 123.7, 122.2, 118.6, 116.0, 47.3, 41.9, 41.6, 30.9; MS (ES+) m/z 480.5 (M+1).
