A solution of 2-fluoro-4-(3-diethylamino-1-propoxy)nitrobenzene (2 mmol; preparation described in Example 5) in THF (5 mL) is treated with 3-diethylamino-1-propylamine (2.4 mmol at rt. After completion of the reaction, the reaction mixture is concentrated in vacuo. The residue is redissolved in EtOAc (10 mL), washed with saturated sodium bicarbonate solution, water, and brine. The organic phase is then dried over sodium sulfate and the solvent is removed in vacuo to afford the product, 2-(3-diethylamino-1-propylamino)-4-(3-diethylamino-1-propoxy)nitrobenzene (620 mg) which was used for further transformation without further purification.
