NaH (12 g, 60%, 300.00 mmol) was added in several batches, to a solution of 1,2,3,4-tetrahydroquinoline (26.6 g, 199.70 mmol) in tetrahydrofuran (150 mL) at 0-5° C. The resulting solution was maintained at 0-5° C. for 30 minutes, then iodomethane (50 g, 352.11 mmol) was added dropwise (at 0-5° C.). The resulting solution was then stirred at room temperature overnight. The mixture was filtered, and the filtrate was purified by column chromatography using a 1:100 ethyl acetate/petroleum ether solvent system to afford 19 g (61%) of 1-methyl-1,2,3,4-tetrahydroquinoline as a yellow liquid.
