실험 절차
Methyl-3-bromothieno[2,3-c]pyridine-5-carboxylate (635 mg, 2.33 mmol) is combined with 25 ml MeOH. The mixture is treated with 2N NaOH (3 ml, 6 mmole) and 3 ml H2O and the reaction is stirred 4 h at rt. The volatiles are removed in vacuo and the residue is combined with 5 ml H2O. The pH of the mixture is adjusted to 3.5 with 10% aqueous HCl. The tan precipitate is collected, washed with water, and is dried in vacuo at 50° C. to afford 475 mg (79%) of 3-bromothieno[2,3-c]pyridine-5-carboxylic acid as a tan solid. MS (ESI): 257.9.
