Following the procedure as described in Example 2, making variations as required to replace pyridin-3-ylmethanamine with 3,4-difluorobenzylamine and replace (S)-2-(3-(4-fluorobenzyl)-4-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid with (R)-2-(3-(4-fluorobenzyl)-4-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid the title compound was obtained as a white solid: mp 134-135° C. (diethyl ether/hexanes); 1H NMR (300 MHz, DMSO-d6) δ 8.54 (t, J=5.9 Hz, 1H), 7.44-7.30 (m, 4H), 7.21-7.12 (m, 3H), 4.60 (d, J=15.6 Hz, 1H), 4.35 (d, J=5.9 Hz, 2H), 4.30 (d, J=15.6 Hz, 1H), 4.19 (dd, J=10.0, 9.1 Hz, 1H), 3.80-3.69 (m, 1H), 3.55 (dd, J=10.0, 6.8 Hz, 1H), 2.47 (s, 3H), 1.22 (d, J=6.2 Hz, 3H); MS (ES+) m/z 475.0 (M+1).
