Triphenylphosphine → HCID 22646612, compound

Participants

Reaction Steps

Diethyl azodicarboxylate (340 mg, 2 mmol) was added dropwise to a solution of triphenylphosphine (520 mg, 2 mmol), 4-chloro-7-hydroxy-6-methoxyquinoline (265 mg, 1.26mmol), (prepared as described for the starting material in Example 3), and 3-(3-pyridyl)-1-propanol (170 mg, 1.24 mmol) in methylene chloride (10 ml). The mixture was stirred for 1 hour at ambient temperature. The volatiles were removed by evaporation and the residue was purified by column chromatography eluting with methylene chloride/acetonitrile/methanol (50/45/5 increasing to 50/40/10). The purified product was triturated with ether, collected by filtration and dried under vacuum to give 4-chloro-6-methoxy-7-(3-(3-pyridyl)propoxy)quinoline (300 mg, 72%).
