실험 절차

Sodium hydride (0.12 g of 60% dispersion in mineral oil, 3 mmol) was added to a solution of 4-(3-benzenesulfonyl-1H-indol-7-yl)-piperazine-1-carboxylic acid tert-butyl ester (1 g, 2.3 mmol) in 20 mL of DMF with ice cooling. After stirring 15 min at room temperature the mixture was treated with methyl iodide (0.17 mL, 3 mmol). Water was added and the mixture was extracted with ethyl acetate. The extract was washed with water and brine, dried (sodium sulfate) and evaporated. Silica gel chromatography (20% ethyl acetate-hexane) afforded 0.9 g of 4-(3-benzenesulfonyl-1-methyl-1H-indol-7-yl)-piperazine-1-carboxylic acid tert-butyl ester as a foam, mass spec. M+ 455.
