Reaction Steps

4-(4-Ethyl-2-fluoro-phenylamino)-1-methyl-6-oxo-1,6-dihydro-pyridine-3-carboxylic acid (0.50 g, 1.72 mmol) was reacted with pentafluorophenyl trifluoroacetate (0.92 mL, 5.20 mmol) in the presence of pyridine (0.45 mL) in DMF (15 mL). The solution was allowed to stir at room temperature for 15 hours and then treated with 2-Amino-ethanol (0.50 mL, 8.60 mmol) as in example 75 to afford the 4-(4-Ethyl-2-fluoro-phenylamino)-1-methyl-6-oxo-1,6-dihydro-pyridine-3-carboxylic acid (2-hydroxy-ethyl)-amide (0.47 g, 82%). 1H NMR [400 MHz, (CD3)2SO] δ 9.82 (s, 1H), 8.35 (t, J=5.4 Hz, 1H), 8.20 (s, 1H), 7.27 (t, J=8.4 Hz, 1H), 7.12 (d, J=11.8 Hz, 1H), 7.06 (d, J=7.7 Hz, 1H), 5.38 (s, 1H), 4.72 (t, J=5.1 Hz, 1 H, OH), 3.44 (t, J=11.5, 6.2 Hz, 2H), 3.35 (s, 3H), 3.22 (t, J=12.8, 6.8 Hz, 2H), 2.58 (q, J=7.1 Hz, 2H), 1.14 (t, J=7.1 Hz, 3H). (APCI+) calcd for C17H20FN3O3 333.36 (M+1), found 334.1.
