Versuchsvorschrift

2-Amino-2,3-dimethylbutyramide (9.84 g, 0.076 mol) is added to a stirred suspension of thieno[2,3-b]pyridine-5,6-dicarboxylic acid anhydride (14.8 g, 0.072 mol) in THF under an inert atmosphere of N2 at room temperature. The dark solution is stirred at room temperature overnight and the resulting solid filtered off, washed with THF and air dried to give 17.35 g (72%) of 6-[(1-carbamoyl-1,2-dimethylpropyl)carbamoyl]thieno[2,3-b]pyridine-5-carboxylic acid.
