実験手順
2-Nitro-4-(quinolin-4-yloxy)-phenol (prepared as described in Example 40, 3.1 g, 11 mmol, 1.0 eq.) was suspended into MeOH (100 mL) and the atmosphere was replaced by argon. The catalyst, 10% Pd/C, was added and the argon was replaced by a H2 atmosphere. The mixture was stirred for 16 h at balloon pressure at RT until TLC showed reaction done. The Pd/C was filtered, the MeOH removed and the crude was purified by column chromatography (10-100% EtOAc/Hexane to 2% MeOH/EtOAc) to yield 2-amino-4-(quinolin-4-yloxy)-phenol.
