Versuchsvorschrift

To a solution of N-(4-chlorobenzyl)-4-hydroxy-8-iodo-6-(tetrahydro-2H-pyran-4-ylmethyl)-3-quinolinecarboxamide (0.185 g), PdCl2(PPh3)2 (0.012 g), and CuI (0.032 g) in 10 mL of diethylamine is added propargyl alcohol (0.02 mL). The reaction is stirred overnight. The mixture is concentrated and the resulting solid is partitioned between CH2Cl2 and water. The aqueous layer is extracted with CH2Cl2 (3×). The combined organic layers are washed with brine, dried and condensed. The crude product is chromatographed (Biotage flash 40S, gradient from CH2Cl2 to 2% MeOH/CH2Cl2). Fractions homogeneous by TLC are combined and concentrated. The resulting solid is recrystallized from CH2Cl2/Et2O to yield 0.09 g (56%) of N-(4-chlorobenzyl)-2-(hydroxymethyl)-6-oxo-8-(tetrahydro-2H-pyran-4-ylmethyl)-6H-pyrrolo[3,2,1-ij]quinoline-5-carboxamide as a white solid, m.p. 196-198° C.
