Lithium indenide (9.60 g, 0.0786 moles) in diethylether (100 mL) was added dropwise to a solution of dimethylsulfate (9.91 g, 0.0786 moles) in diethylether (125 mL) over a period of 15 minutes. After the addition was complete, H2O (150 mL) was added to the reaction. The organic layer was then separated and washed with H2O (2×100 mL). Drying over MgSO4 followed by filtration and solvent removal yielded the desired product as a yellow oil (9.68 g, 94.7 percent).
