Reaction Steps

N-Ethyl-3-nitro-N-phenylaniline (400 mg, 1.65 mmol) was dissolved in acetic acid (5 ml) at 40° C. followed by slow addition of tin (II) chloride dihydrate (1.50 g, 6.60 mmol). The reaction mixture was stirred at 40° C. for 2 hours and then for a further 2 hours at 75° C. The mixture was concentrated in vacuo and the obtained residue was diluted with ether (10 ml). Aqueous sodium hydroxide solution (2 ml) was added dropwise to the cooled (0° C.) solution. A solid formed was separated by filtration and was rinsed twice with hot ethyl acetate (25 ml). The filtrate was concentrated to approximately 30 ml and washed with 1 N sodium hydroxide, brine, dried over sodium sulfate and concentrated in vacuo to give N-ethyl-N-phenylbenzene-1,3-diamine as a yellow oil (117 mg, 1.04 mmol, 63% yield). 1H NMR (400 MHz, CDCl3): 6.87-7.28 (m, 7H), 6.28-6.83 (m, 2H), 3.74 (q, 2H), 3.59 (s, 2H), 1.20 (t, 3H); MS (EI) for C14H16N2: 212 (MH+).
