Using an analogous procedure and workup as described in for the preparation of intermediate I-15b above. (E-1,2-difluoro-4-(2-nitrovinyl)benzene (I-49a: 5 g, 27.027 mmol) in dry THF (81 mL) as reacted with LiBH4 (2.35 g, 108.1081 mmol) and chloro trimethyl silane (27.63 ml, 216.216 mmol) at 0° C. The resulting mixture was stirred at room temperature for 3 days to afford 4.2 g of the product (100% yield).
