実験手順
Lithium bis(trimethylsilyl)amide (1.0M in tetrahydrofuran, 2.80 mL, 2.80 mmol) was added dropwise to a stirred suspension of 6-bromoindolin-2-one (preparation 1, 0.20 g, 0.94 mmol) in tetrahydrofuran (1.5 mL) at 0° C. The mixture was stirred for 15 minutes, then tert-butyl bis(2-chloroethyl)carbamate (0.25 g, 1.04 mmol) in THF (1 mL) was added dropwise and the mixture was warmed to room temperature. After stirring overnight, 2M aqueous hydrochloric acid was added to the reaction and the mixture was extracted with ethyl acetate. The organic layer was dried (MgSO4) and evaporated. Purification of the residue by flash chromatography (5:1 hexanes/ethyl acetate) gave the title compound (0.08 g, 22%) as a yellow solid.
