Reaction Steps

Following the procedure as described in Example 32, making variations as required to replace 2-(3-((5-chlorobenzo[b]thiophen-3-yl)methyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid with 4-methyl-2-(2-oxo-3-((5-phenyloxazol-4-yl)methyl)imidazolidin-1-yl)thiazole-5-carboxylic acid to react with 3-(aminomethyl)-pyridine, the title compound was obtained as a colorless solid in 13% yield: mp 78-81° C. (dichloromethane/hexanes); 1H NMR (300 MHz, CDCl3) δ 8.59 (s, 1H), 8.54 (d, J=4.8 Hz, 1H), 7.89 (s, 1H), 7.72-7.69 (m, 3H), 7.50-7.36 (m, 3H), 7.30-7.27 (m, 1H), 6.04-6.00 (m, 1H), 4.68 (s, 2H), 4.58 (d, J=5.8 Hz, 2H), 4.11-4.05 (m, 2H), 3.73-3.67 (m, 2H), 2.62 (s, 3H); MS (ES+) m/z 475.2 (M+1).
