実験手順
A solution of 2-(4-aminophenyl)-6-ethoxy-1-ethyl-1H-indole-3-carbonitrile (148 mg, 0.484 mmol), diethyl chlorophosphate (0.086 mL, 0.58 mmol) and diisopropylethylamine (0.10 mL, 0.57 mmol) in 1,4-dioxane (5 mL) is stirred at ambient temperature for 12 hours, then heated to 80° C. for an additional 24 hours. The solution is cooled and poured into 50 mL of ethyl acetate. This is washed with water and saturated brine (50 mL each), then dried over anhydrous magnesium sulfate, filtered and evaporated. The residual material is separated by flash chromatography (eluting 2/1 ethyl acetate/hexane on silica gel 60) to afford diethyl [4-(3-cyano-6-ethoxy-1-ethyl-1H-indol-2-yl)-phenyl]-phosphoramidate (108 mg, 0.245 mmol, 51%) as a white powder after evaporation.
