Following the procedure as described in Example 16, making variations as required to replace N-benzyl-2-(3-(2,2-dimethoxyethyl)-3-(4-fluorobenzyl)ureido)-4-methylthiazole-5-carboxamide with 2-(3-(2,2-dimethoxyethyl)-3-(4-fluorobenzyl)ureido)-4-methyl-N-(pyridin-3-ylmethyl)thiazole-5-carboxamide, the title compound was obtained as a colorless solid in 96% yield: mp 64-66° C. (ethyl acetate/hexanes); 1H NMR (300 MHz, CDCl3) δ 8.64-8.45 (m, 2H), 7.68-7.63 (m, 1H), 7.30-7.10 (m, 3H), 7.05-6.97 (m, 2H), 6.57 (br s, 1H), 6.04-5.75 (m, 2H), 4.56 (d, J=6.0 Hz, 2H), 4.48 (s, 2H), 3.62-3.56 (m, 1H), 3.29-3.25 (m, 1H), 2.52 (s, 3H); 13C NMR (75 MHz, CDCl3) δ 162.5, 162.4, 157.0, 153.7, 148.9, 135.7, 135.0, 133.9, 131.0, 129.9, 123.6, 117.4, 116.0, 115.7, 60.4, 49.5, 46.7, 41.4, 17.2; MS (ES+) m/z 442.3 (M+1).
