Versuchsvorschrift

2-Nitro-6,7-dihydrobenzo[b]thiophen-4(5H)-one (3.6 g, 18.2 mmol) was dissolved in DMF (50 mL) and stirred under an atmosphere of hydrogen (300 psi) for 18 hr with 10% palladium on carbon. The mixture was filtered through celite and used directly in the next step as a solution in DMF.
