Versuchsvorschrift
Using analogous conditions and workup as described for the preparation of I-14b above, (E)-5-fluoro-2-(2-nitrovinyl)benzo[b]thiophene (I-50d: 1.2 g, 5.375 mmol) was reacted with LiBH4 (468.34 mg, 21.503 mmol), trimethylsilyl chloride (4.649 g, 43 mmol) and THF (50 mL) to afford 1 g of the product (100% yield). LCMS: 98.10%, m/z=196.0 (M+1)
