반응 단계
To a solution of indole-4-carboxylic acid (506 mg, 3.14 mmol) dissolved in a mixture of methanol (5 mL) and diethyl ether (10 mL) was added ethereal diazomethane until disappearance of starting acid was indicated by TLC. Anhydrous magnesium sulfate was then added and the solution filtered and concentrated in vacuo. Flash chromatography on 10 g of Merck silica gel eluted with 2:1, chloroform:hexanes, followed by 10:1, chloroform:diethyl ether afforded the title compound (540 mg, 98%).
