実験手順

A solution of N-(4-chlorobenzyl)-4-hydroxy-8-iodo-6-(tetrahydro-2H-pyran-4-ylmethyl)-3-quinolinecarboxamide (0.16 g), PdCl2(PPh3)2, CuI (0.018 g) and 3-butyn-1-ol (0.03 mL) in 15 mL Et2NH is stirred at room temperature for 7 days. The solid in the reaction is filtered and rinsed with EtOAc. The filtrate is partitioned between EtOAc and H2O. The aqueous layer is extracted with EtOAc (3×). The organic layers and the solid previously filtered are combined, concentrated, adsorbed onto silica and chromatographed (gradient from CH2Cl2 to 4% MeOH in CH2Cl2). Product-containing fractions are combined and condensed to afford 101.6 mg (71%) of N-(4-chlorobenzyl)-2-(2-hydroxyethyl)-6-oxo-8-(tetrahydro-2H-pyran-4-ylmethyl)-6H-pyrrolo[3,2,1-ij]quinoline-5-carboxamide as a tan solid.
