実験手順

5-(1-Carboxy-1-methyl-ethoxy)-2-methyl-1H-indole-3-carboxylic acid benzyl ester (1.0 g, 2.76 mmol, 1.0 eq) was dissolved in ethylacetate (100 mL), and treated with diethylamine (0.241 g, 3.3 mmol, 1.2 eq) followed by HBTU (0.446 g, 3.3 mmol, 1.2 eq). The reaction mixture was stirred at room temperature for 24 hours and was followed by TLC (hexane/ethyl acetate 1/1). The reaction was quenched with aqueous sodium bicarbonate, extracted with ethyl acetate, and the organic layers dried over sodium sulfate, evaporated, and loaded on silica gel, followed by flash chromatography (hexane/ethyl acetate 1/1). 0.109 g of the product was obtained, 12% yield. LC/MS (ESI+) 422.52 (M+1) (C25H30N2O4).
