Following the procedure as described in Example 2, making variations as required to replace pyridin-3-ylmethanamine with (5-methylpyrazin-2-yl)methanamine and replace (S)-2-(3-(4-fluorobenzyl)-4-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid with (R)-2-(3-(3,5-difluorobenzyl)-4-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid, the title compound was obtained as a white solid: mp 131-132° C. (ethanol/water); 1H NMR (300 MHz, DMSO-d6) δ 8.58 (t, J=5.7 Hz, 1H), 8.47-8.46 (m, 2H), 7.19-7.08 (m, 3H), 4.60-4.37 (m, 4H), 4.23 (t, J=9.6 Hz, 1H), 3.87-3.80 (m, 1H), 3.59 (dd, J=10.1, 6.7 Hz, 1H), 2.48 (s, 3H), 2.47 (s, 3H), 1.22 (d, J=6.2 Hz, 3H); MS (ES+) m/z 473.0 (M+1).
