Procedure
4-[2-Fluoro-4-(3-hydroxy-1-propynyl)anilino]-N-(3-hydroxypropyl)-1-methyl-6-oxo-1,6-dihydro-3-pyridinecarboxamide was hydrogenated in MeOH in the presence of 5% Pd/C for example 3. Purification of the crude oil was carried out by column chromatography on silica gel (5% MeOH/CH2Cl2 as eluant) to give 4-[2-fluoro-4-(3-hydroxypropyl)anilino]-N-(3-hydroxypropyl)-1-methyl-6-oxo-1,6-dihydro-3-pyridinecarboxamide as a white solid (92%), m.p. (CH2Cl2/MeOH) 161-164° C. 1H NMR [(CD3)2SO, 400 MHz] δ 9.88 (s, 1H), 8.36 (t, J=5.4 Hz, 1H), 8.21 (s, 1H), 7.33 (t, J=8.3 Hz, 1H), 7.17 (dd, J=11.9, 1.7 Hz, 1H), 7.06 (dd, J=8.1, 1.4 Hz, 1H), 5.42 (d, J=0.9 Hz, 1H), 4.48 (t, J=5.0 Hz, 1H), 4.09 (q, J=5.2 Hz, 1H), 3.47 (q, J=5.9 Hz, 2H), 3.41 (q, J=6.0 Hz, 2H), 3.35 (s, 3H), 3.26 (q, J=6.6 Hz, 2H), 2.62 (t, J=7.7 Hz, 2H), 1.75-1.62 (m, 4H). Anal. Calcd for C19H24FN3O4.0.5H2O; C, 59.1; H, 6.5; N, 10.9. Found: C, 59.3; H, 6.4; N, 10.9.
