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-(2-cyclopropylethyl)-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 87% yield: mp 148-150° C.; 1H NMR (300 MHz, CDCl3) δ 8.58 (s, 1H), 8.52 (s, 1H), 7.74 (s, 1 H), 7.69 (d, J=7.7 Hz, 1H), 7.27 (s, 1H), 6.87 (s, 1H), 6.44 (t, J=5.7 Hz, 1H), 4.60 (d, J=5.7 Hz, 2H), 3.91 (t, J=7.0 Hz, 2H), 2.50 (s, 3H), 1.70-1.61 (m, 2H), 0.75-0.60 (m, 1 H), 0.47-0.39 (m, 2H), 0.06-−0.02 (m, 2H); 13C NMR (75 MHz, CDCl3) δ 162.6, 150.5, 149.2, 149.0, 140.8, 135.6, 134.7, 131.6, 125.0, 123.7, 119.9, 46.0, 41.4, 33.4, 16.0, 8.1, 4.0: MS (ES+) m/z 384.4 (M+1).
