Reaktionsschritte

380 mL 1N LiHMDS-solution in n-hexane was added to 20 g 4-fluoro-benzonitrile in 1 L diethylether. The reaction was stirred for 2 h at RT and decomposed with 1 L 4 NHCL-solution at 0° C. 4 N sodium hydroxide was added until pH 12 was reached and the water layer was extracted with chloroform. The organic layer was dried and evaporated to give 6.6 g of the desired product. Rt: 0.30 min (method B), (M+H)+: 139
