Trimethylsilyldiazomethane → HCID 58056214, compound

Participants

Reaction Steps

Trimethylsilyldiazomethane (2 M in hexane, 1 mL) was added to a suspension of thieno[3,2-d]pyrimidine-7-carboxylic acid (50 mg) in a mixture of dichloromethane and methanol (95/5, 1 mL) and the resulting mixture was stirred at room temperature for 1 hour. The reaction mixture was then evaporated under reduced pressure and the crude residue was purified by flash chromatography (DCM/MeOH, 97/3) to give 40 mg of thieno[3,2-d]pyrimidine-7-carboxylic acid methyl ester.
