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, approximately 9 mL) over two minutes at room temperature. The yellow mixture is concentrated under reduced pressure. The residue is redissolved in methanol and concentrated under reduced pressure several times to give the title compound as a solid (100%). ES/MS m/e 256.0 (M+2).
