Yield: 87.97%

Reaction Conditions:

in tetrahydrofuran at 0; for 12 h;Inert atmosphere;

Steps:

4.1.15. The synthesis of intermediate 29
The 1H-indole-5-carboxylic acid (1.5 g, 9.31 mmol) was dissolvedin THF under Ar atmosphere and CH3Li (1.5 M, 20.48 mL,30.71 mmol) was added dropwise at 0 °C. After stirring for 12 h, thereactionwas quenched with water, extracted with EA (3 x 150 mL), and the combined organic layers were then washed with brine,dried over anhydrous Na2SO4, and concentrated in vacuo to providethe crude product, which was purified by column chromatographywith petroleum/ethyl acetate (4: 1) to give 29 (1.30 g, 87.97%) as ayellow oil. The spectra data were consistent with the literature [29].
