Reaction Steps

A stirred solution of ethyl 6-(6,7-diphenyl-1,8-naphthyridin-2-yl)hexanoate (step 2)(280 mg, 0.660 mmol) in EtOH (10 ml) under an atmosphere of argon was treated with 10% palladium on carbon (70.2 mg), purged three times with nitrogen and placed under an atmosphere of hydrogen overnight. The mixture was filtered through Celite® (filter material) and the catalyst was washed with EtOAc (100 ml). The filtrate was concentrated in vacuo to yield the title compound as an off white solid. Purification of the crude product by chromatography on silica eluting with 0-100% EtOAc in iso-hexane afforded the title compound as a yellow oil.
