실험 절차

A solution of N-(4-chlorobenzyl)-8-iodo-1-methyl-4-oxo-6-(tetrahydro-2H-pyran-4-ylmethyl)-1,4-dihydro-3-quinolinecarboxamide (0.074 g), copper iodide (0.013 g), Pd(PPh3)2Cl2 (0.007 g) and 3-butyn-1-ol (0.02 mL) in 7 mL diethylamine is stirred at room temperature for 3 days. The reaction is partitioned between CH2Cl2 and H2O. The aqueous is extracted 3×with CH2Cl2. The organics are combined, dried over Na2SO4, filtered and concentrated. The residue is dissolved in CH2Cl2 and adsorbed onto silica. Purification by Biotage Flash 40S chromatography (eluent CH2Cl2 (1L), 0.5% MeOH/CH2Cl2 (1L), 1% MeOH/CH2Cl2 (1L), 1.5% MeOH/CH2Cl2 (1L), 2% MeOH/CH2Cl2 (1L), 3% MeOH/CH2Cl2 (1L), 5% MeOH/CH2Cl2 (1L), 7% MeOH/CH2Cl2 (1L)) affords the product as a tan residue. The residue is dissolved in a minimal amount of CH2Cl2 and hexanes are added to affect recrystallization. The solution is placed in the freezer for 18 h after which the product is collected and dried (0.037 g, 57%).
