実験手順

To a stirred solution of 2,4,6-trifluoronitrobenzene (5.31 g, 30 mmol), TEA (8.37 mL, 60 mmol) and DMF (50 mL) was added dropwise a solution of n-butylamine (2.96 mL, 30 mmol) in DMF (20 mL) at rt following General Procedure G1 to obtain crude 2-butylamino-4,6-difluoronitrobenzene (9.0 g). This product was mixed with 3-diethylaminopropanol (11.1 mL, 75 mmol) and anhydrous THF (150 mL), and then powdered KOBut (8.5 g, 75 mmol) was added following General Procedure G2 to afford crude 2-butylamino-4,6-di(3-diethylaminopropoxy)nitrobenzene (15.5 g).
