Reaktionsschritte

To a solution of 1 g (7.5 mmol) of 2-methyl-2,3-dihydro-1H-indole in anhydrous DMF were added 1.03 g (7.5 mmol) of K2CO3 and then dropwise 0.97 mL (8.0 mmol) of benzylbromide. The mixture was stirred at RT for 3hrs and then distributed between Et2O and a saturated aqueous solution of NH4Cl. The combined organic phases were dried over Na2SO4 and evaporated to yield 1.7 g (quantitative) of crude 1-benzyl-2-methyl-2,3-dihydro-1H-indole, light blue oil, MS: 224 (MH+).
