Reaction Steps
To a solution containing 2.76 g of 4-nitroaniline (20 mmol) in 20 mL DMF was added 1.60 g of NaH (60% dispension in oil, 40 mmol). After 2 hours at room temperature, 2-(dimethylamino)ethyl chloride hydrochloride (3.46 g, 24 mmol) was added, and the reaction mixture was heated at 60° C. for 12 hours. The solvent was evaporated in vacuo to yield a residue which was partitioned between ethyl acetate and brine. The organic phase was dried over anhydrous sodium sulphate, filtered, and concentrated in vacuo to yield a residue. Purification of the residue by flash chromatography with 2% MeOH in CH2Cl2 as the eluent yielded N,N-dimethyl-N′-(4-nitro-phenyl)-ethane-1,2-diamine (2.34 g, 56%) and the title compound (1.23 g, 22%). MS (ES+) m/e 281 [M+H]+.
