Procedure

To a stirred slurry of 1.15 g of 1-(tert-butyl)-N-(4-chlorobenzyl)-6-iodo-4-oxo-1,4-dihydro-3-quinolinecarboxamide from Preparation No. 10, 156 mg of copper (I) iodide, and 66 mg of dichlorobis(triphenylphosphine)palladium (II) in 23 mL of diethylamine, under argon, is added 0.16 mL of propargyl alcohol. The mixture is stirred for 18 hour at room temperature, then concentrated under reduced pressure. The residue is partitioned between water and chloroform-methanol, and the organic phase dried (MgSO4) and concentrated under reduced pressure. Flash chromatography of the residue on silica using 2-4% methanol in dichloromethane affords 977 mg of tan solid. Recrystallization from ethanol provides 850 mg of the title compound as a beige solid.
