Versuchsvorschrift

To a solution of 2-methyl-2-(2-methylquinolin-8-yl)propan-1-ol (0.43 g, 2.00 mmol) and iodomethane (0.37 mL, 5.99 mmol) in DMSO (10 mL) was added NaH (0.16 g, 3.99 mmol) at ambient temperature and stirred at ambient temperature for 30 minutes. Water (10 mL) and ether (40 mL) were added. The organic layer was separated, washed with brine, dried (sodium sulfate), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (5:1 hexane/ethyl acetate) to give 8-(1-methoxy-2-methylpropan-2-yl)-2-methylquinoline (0.43 g, 93.0%) as an oil.
