Mode opératoire

Ethyl 3-ethynyl-6-nitro-1-benzothiophene-2-carboxylate obtained in Example (183d) was dissolved in methanol (16 mL) and THF (24 ml). A 10% palladium-carbon catalyst (120 mg) was added, and the mixture was stirred in a hydrogen atmosphere throughout the day. The reaction solution was filtered through celite and then concentrated under reduced pressure to obtain the title compound. The resulting compound was used for the next reaction without purification.
