Procedure

To a suspension of N-(4-chlorobenzyl)-8-iodo-1-methyl-6-(morpholin-4-ylmethyl)-4-oxo-1,4-dihydroquinoline-3-carboxamide (300 mg), PdCl2(PPh3)2 (19.1 mg), and CuI (5.2 mg) in Et2NH (6.2 mL) and anhydrous DMF (10 mL) is added 4,5-dichloro-1-prop-2-ynylimidazole (104.8 mg). The reaction is sonicated and stirred at room temperature for 2 days. The reaction is condensed to afford a residue. The residue is adsorbed onto silica and chromatographed (eluant 100% CH2Cl2 (1L), 0.5% MeOH in CH2Cl2 (1L), 1% MeOH in CH2Cl2 (1L), 1.5% MeOH in CH2Cl2 (1L), and 2% MeOH in CH2Cl2 (3L)). Product-containing fractions are combined and condensed to afford 20 mg of the title compound as a white solid.
