4-(2-Fluoro-4-iodoanilino)-N-(2-hydroxyethyl)-1-methyl-6-oxo-1,6-dihydro-3-pyridinecarboxamide was reacted with propargyl alcohol in the presence of CuI, (Ph3P)2PdCl2 and TEA in THF/DMF (1:1) as for example 2. The residue resulting from removal of the reaction solvents under reduced pressure was purified by column chromatography on silica gel (10% MeOH/CH2Cl2 as eluant) to give 4-[2-fluoro-4-(3-hydroxy-1-propynyl)anilino]-N-(2-hydroxyethyl)-1-methyl-6-oxo-1,6-dihydro-3-pyridinecarboxamide as a cream solid (79%). 1H NMR [(CD3)2SO, 400 MHz] δ 10.26 (s, 1H), 8.44 (t, J=5.4 Hz, 1H), 8.30 (s, 1H), 7.48 (t, J=8.4 Hz, 1H), 7.38 (dd, J=11.6, 1.8 Hz, 1H), 7.27 (dd, J=8.3, 1.4 Hz, 1H), 5.70 (s, 1H), 5.35 (t, J=5.9 Hz, 1H), 4.76 (t, J=5.7 Hz, 1H), 4.30 (d, J=6.0 Hz, 2H), 3.50 (q, J=5.8 Hz, 2H), 3.38 (s, 3H), 3.31-3.26 (m, 2H). LCMS (APCI+) calcd for C18H18FN3O4 360 (MH+), found 360.
