Following the procedure as describe in Example 12, making variations as required to replace (5-fluoropyridin-3-yl)methanamine with pyridin-2-ylmethanamine to react with 2-(3-isobutyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid in place of 2-(3-(cyclopropylmethyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid, the title compound was obtained as a colorless solid in 46% yield: 1H NMR (300 MHz, CDCl3) δ 8.52-8.50 (m, 1H), 7.65-7.60 (m, 1H), 7.26-7.23 (m, 1H), 7.18-7.14 (m, 1H), 7.11-7.06 (m, 1H), 4.66 (d, J=5.6 Hz, 2H), 4.10-4.05 (m, 2H), 3.58-3.53 (m, 2H), 3.09 (d, J=7.5 Hz, 2H), 2.61 (s, 3H), 1.94-1.85 (m, 1H), 0.91 (d, J=6.4 Hz, 6H); 13C NMR (75 MHz, CDCl3) δ162.5, 157.6, 155.8, 155.6, 152.3, 148.8, 136.5, 122.2, 121.7, 117.7, 51.4, 44.5, 42.7, 41.9, 26.6, 19.8, 17.1; MS (ES+) m/z 373.8 (M+1).
