Trimethylsilyldiazomethane → Methyl 6-Bromo-1H-Indole-3-Carboxylate

Participants

Reaction Steps

To a solution of 6-bromoindole-3-carboxylic acid (960 mg, 4.00 mmol) in methanol (9.5 mL) is added (trimethylsilyl)diazomethane (2.0 M solution in hexanes, about 9 mL) over two minutes at room temperature. The yellow mixture is concentrated under reduced pressure. The residue is re-dissolved in methanol and concentrated under reduced pressure. This process is repeated several times to give the title compound as a solid (100%). ES/MS m/e 256.0 (M+2).
