実験手順: coupling 3-isopropylindole with 4-methoxybenzenethiol to give 3-isopropyl-2-(4-methoxyphenylthio)indole (yield: 72% of pure product);

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Stir a mixture of 3-isopropyl indole in dry DMF (20 ml) under N2 add potassium t-butoxide 1.0 M (1.2 ml, 1.2 mmol) dropwise. Stir the resulting solution for 30 minutes at ambient temperature. Add 4-(4-Fluoro-benzylcarbamoyl)-benzenesulfonyl chloride (0.360 g, 1.1 mmol) portionwise and stir the resulting mixture overnight. Pour the reaction mixture into a mixture of EtOAc—H2O. Separate the EtOAc layer, extract with H2O wash with brine and dry (MgSO4). Filter and evaporate to give the crude product. Chromatograph on the ISCO eluting with hexane-EtOAc to give a white solid (0.150 g). Mass spectrum (m/e) (M+H) 451.1492; found 451.1488. Stir the resulting solution for 30 minutes at ambient temperature Pour the reaction mixture Separate the EtOAc layer extract with H2O wash with brine dry (MgSO4) Filter evaporate to give the crude product Chromatograph on the ISCO eluting with hexane-EtOAc

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Add potassium tert butoxide 1.0 M (1.6 mL, 0.0016 mol) dropwise to a stirring solution of 3-isopropyl indole (0.217 g, 00136 mol) in dry DMF (20 mL) under N2 at ambient temperature. Stir the reaction mixture for 30 minutes and add portionwise 4-chlorosulfonyl benzoic acid methyl ester (0.328 g, 0.0014 mol). The light brown reaction mixture decolorizes immediately. Stir the resulting yellow solution overnight. Pour into a EtOAc—H2O mixture (100 to 300 mL). Separate the EtOAc and sequentially extract with H2O (3×250 mL), wash with brine, dry (MgSO4), filter and evaporate giving 0.38 g. Chromatograph on the ISCO using a gradient hexane-EtOAc (0-50%, 30 30 minutes) to give 0.249 g (51%) of the title compound as a waxy solid. Mass spectrum (m/e) (M+H) 358.1113. found (M+H) 358.1129. Stir the resulting yellow solution overnight Separate the EtOAc sequentially extract with H2O (3×250 mL) wash with brine dry (MgSO4) filter evaporate giving 0.38 g
