Following the procedure as described in Example 2, making variations as required to replace pyridin-3-ylmethanamine with (1-methyl-1H-pyrazol-4-yl)methanamine and replace (S)-2-(3-(4-fluorobenzyl)-4-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid with (S)-2-(3-(4-fluorobenzyl)-5-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid, the title compound was obtained as a white solid (70%): mp 176-177° C. (N,N-dimethylformamide/water); 1H NMR (300 MHz, DMSO-d6) δ 8.28 (t, J=5.7 Hz, 1H), 7.56 (s, 1H), 7.36-7.32 (m, 3H), 7.23-7.17 (m, 2H), 4.57-4.50 (m, 1H), 4.42 (d, J=4.4 Hz, 2H), 4.19 (d, J=5.7 Hz, 2H), 3.78 (s, 3H), 3.63-3.57 (m, 1H), 3.03 (dd, J=9.0, 3.4 Hz, 1H), 2.46 (s, 3H), 1.38 (d, J=6.0 Hz, 3H); MS (ES+) m/z 443.1 (M+1).
