Participants

Reaction Steps

Following the procedure as describe in Example 12, making variations as required to replace (5-fluoropyridin-3-yl)methanamine with oxazol-2-ylmethanamine 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 58% yield: 1H NMR (300 MHz, CDCl3) δ 7.63 (s, 1H), 7.07 (s, 1H), 6.34-6.37 (m, 1H), 4.70 (d, J=5.3 Hz, 2H), 4.16-4.11 (m, 2H), 3.64-3.58 (m, 2H), 3.43-3.39 (m, 2H), 2.63 (s, 3H), 2.21-2.08 (m, 2H), 1.91-1.81 (m, 2H); 13C NMR (75 MHz, CDCl3) δ 162.4, 160.6, 157.6, 155.6, 153.4, 139.2, 127.2, 117.2, 42.9, 42.3, 42.0, 37.2, 31.7, 31.3, 30.9, 30.6, 20.2, 17.3; MS (ES+) m/z 417.7 (M+1).
