Reaction Steps

A suspension of 5-cyclopropylethynyl-3-nitrothiophene-2-carboxylic acid methyl ester (104 mg) and palladium (10% on carbon, 10 mg) in methanol (10 mL) was vigorously stirred under an atmosphere of hydrogen at atmospheric pressure for 5 hours. The catalyst was then filtered off with suction, and the filtrate was concentrated. The product with the molecular weight of 225.31 (C11H15NO2S); MS (ESI): 226 (M+H+).
