To a stirred mixture of 2-methylquinolin-7-ol (0.400 g, 2.51 mmol), Cs2CO3 (2.46 g, 7.54 mmol) and DMF (16 mL) was added (R)-2-methyloxirane (0.438 g, 7.54 mmol). The reaction mixture was heated at 80° C. for 2 hours. After cooling, the reaction mixture was partitioned between ether and water. The aqueous layer was extracted with ether. The combined organic layers were washed with water and brine, dried and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (1% MeOH in EtOAc) to give (R)-1-(2-methylquinolin-7-yloxy)propan-2-ol (0.471 g, 86%).
