Following the procedure as describe in Example 12, making variations as required to replace (5-fluoropyridin-3-yl)methanamine with (1-methyl-1H-pyrazol-4-yl)methanamine to react with 4-methyl-2-(2-oxo-3-(4,4,4-trifluorobutyl)imidazolidin-1-yl)thiazole-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 49% yield: 1H NMR (300 MHz, CDCl3) δ 7.44 (s, 1H), 7.37 (s, 1H), 5.79-5.76 (m, 1H), 4.40 (d, J=5.3 Hz, 2H), 4.15-4.09 (m, 2H), 3.87 (s, 3H), 3.62-3.57 (m, 2H), 3.42-3.37 (m, 2H), 2.60 (s, 3H), 2.19-2.11 (m, 2H), 1.88-1.83 (m, 2H); 13C NMR (75 MHz, CDCl3) δ 162.2, 157.1, 155.6, 152.8, 138.7, 129.4, 118.2, 117.4, 42.9, 42.3, 42.0, 38.9, 34.4, 31.4, 30.9, 20.2, 17.2; MS (ES+) m/z 430.9 (M+1).
