Participants

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-(pyridin-2-ylmethyl)imidazolidin-1-yl)thiazole-5-carboxylic acid to react with 3-(aminomethyl)pyridine, the title compound was obtained as a colorless solid in 12% yield: mp 58-61° C. (dichloromethane/hexanes); 1H NMR (300 MHz, CDCl3) δ 8.56-8.48 (m, 3H), 7.69-7.64 (m, 2H), 7.31-7.18 (m, 3H), 6.21 (br s, 1H), 4.58 (s, 2H), 4.56 (d, J=6.0 Hz, 2H), 4.09 (t, J=9.0 Hz, 2H), 3.62 (t, J=9.0 Hz, 2H), 2.59 (s, 3H); MS (ES+) m/z 409.2 (M+1).
