Reaction Steps

Following the procedure as described in Example 31, making variations as required to replace 5-(1-(4-fluorobenzyl)-5-oxo-1H-1,2,4-triazol-4(5H)-yl)-3-methylthiophene-2-carboxylic acid with 5-(1-benzyl-5-oxo-1H-1,2,4-triazol-4(5H)-yl)-3-methylthiophene-2-carboxylic acid to react with 3-(aminomethyl)pyridine, the title compound was obtained as a colorless solid in 89% yield: mp 180-181° C.; 1H NMR (300 MHz, CDCl3) δ 8.61 (s, 1H), 8.54 (s, 1H), 7.73 (s, 1H), 7.71 (d, J=8.1 Hz, 1H), 7.43-7.25 (m, 6H), 6.88 (s, 1H), 6.48 (t, J=5.6 Hz, 1H), 5.00 (s, 2H), 4.61 (d, J=5.6 Hz, 2H), 2.52 (s, 3H); 13C NMR (75 MHz, CDCl3) δ 162.6, 150.4, 149.2, 149.0, 140.8, 135.6, 135.3, 134.5, 132.2, 128.8, 128.4, 128.2, 125.1, 120.0, 49.8, 41.4, 16.0: MS (ES+) m/z 406.2 (M+1).
