Methyl 3-amino-2-thiophenecarboxylate → HCID 58556932, compound

Participants

Reaction Steps

To a suspension of 2-oxoacetic acid hydrate (156 mg, 1.70 mmol) and methyl 3-aminothiophene-2-carboxylate (267 mg, 1.70 mmol) in acetonitrile (15 ml), was added 6-methoxypyridin-3-ylboronic acid (260 mg, 1.70 mmol). The reaction was refluxed for 2 hours, and the solvent was evaporated to obtain 2-(2-(methoxycarbonyl)thiophen-3-ylamino)-2-(6-methoxypyridin-3-yl)acetic acid (548 mg, 100% yield). The product was used for the next step without any further purification.
