To a mixture of quinolin-5-ol (2.00 g, 13.8 mmol) and K2CO3 (7.62 g, 55.1 mmol) in DMF (20 mL) was added 2-iodopropane (2.76 mL, 27.6 mmol). The reaction mixture was heated at 80° C. overnight before it was partitioned between EtOAc and water. The layers were separated and the aqueous layer was extracted with EtOAc (2×). The combined organic layers were washed with brine, dried over MgSO4 and concentrated to dryness. The crude material was purified by column chromatography (10-20% EtOAc-Hex) to provide 5-isopropoxyquinoline (91%) as a light yellow oil. ESI-MS m/z calc 187.1, found 188.3 (M+1)+. Retention time: 1.06 minutes (3 min run).
