Participants

Reaction Steps

7-Benzyloxy-6-methoxy-4-(2-methyl-quinolin-3-yloxy)-quinoline (compound 351) (1 g) was dissolved in N,N-dimethylformamide (15 ml) to prepare a solution. 20% Palladium hydroxide (100 mg) was added to the solution, and the mixture was stirred at room temperature under a hydrogen stream overnight. The reaction solution was filtered through Celite, and the solvent was removed from the filtrate by distillation under the reduced pressure. The residue was purified by column chromatography using chloroform-methanol to give the title compound (647 mg, yield 85%).
