Following the procedure as described in EXAMPLE 2, making variations as required to replace pyridin-3-ylmethanamine with pyridin-2-ylmethanamine 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 (72%): mp 112-113° C. (diethyl ether/hexane); 1H NMR (300 MHz, DMSO-d6) δ 8.50-8.46 (m, 2H), 7.75-7.70 (m, 1H), 7.34-7.14 (m, 6H), 4.56-4.51 (m, 1H), 4.46-4.39 (m, 4H), 3.56-3.50 (m, 1H), 3.01 (dd, J=9.1, 3.4 Hz, 1H), 2.46 (s, 3H), 1.36 (d, J=6.2 Hz, 3H); MS (ES+) m/z 439.9 (M+1).
