Potassium Carbonate → HCID 117667312, compound

Participants

Reaction Steps

To a mixture of N-[6-(5-benzyloxy-pyridin-3-yl)-3,4-dihydro-2H-[1,8]naphthyridine-1-carbonyl]-benzamide (620 mg, 1.3 mmol) in EtOH (23 ml) is added potassium carbonate (276 mg, 2.0 mmol). The resultant mixture is heated at reflux for 15 min. After cooling to rt, the solid is removed by filtration and the filtrate is concentrated under vacuum. The residue is dissolved in DCM, washed with water and brine, and is dried (Na2SO4). The solvent is evaporated and the crude product is purified by silica gel column to afford 6-(5-benzyloxy-pyridin-3-yl)-3,4-dihydro-2H-[1,8]naphthyridine-1-carboxylic acid amide (188 mg).
