실험 절차

To a nitrogen flushed solution of 8-fluoro-5-nitroisoquinoline (Description 42; 1.33 g, 6.9 mmol) in methanol (100 ml) was added 10% palladium on carbon (500 mg) and the resulting mixture stirred under a balloon of hydrogen for 3.5 hours. The catalyst was removed by filtration and the filtrate evaporated to dryness. The residue was purifted by MPLC (Biotage Flash™ 40) eluting with 2% MeOH in dichloromethane to give the title compound (450 mg, 40%) as a yellow solid.
