Reaction Steps

A suspension of 5-(4-benzoylpiperazin-1-yl)-2-nitro-N-phenylbenzenamine (0.8 g, 2.0 mmol), and palladium on carbon (40 mg, 5%) in 40 ml ethanol was stirred at room temperature under hydrogen atmosphere overnight. The mixture was filtered with the aid of celite. (4-(4-amino-3-(phenylamino)phenyl)piperazin-1-yl)(phenyl)methanone (0.60 g, 80%) was obtained by flash column chromatograph (60% ethyl acetate in hexanes), ant its hydrochloride was made by bubbling HCl gas in ether solution. 1H NMR (500 MHz, DMSO-d6) δ (ppm) 3.24 (s, br, 4H), 3.53 (s, br, 2H), 3.80 (s, br, 2H), 6.81 (d, J=8.1 Hz, 1H), 6.87 (t, J=7.3 Hz, 1H), 7.26-7.49 (m, 11H), 8.56 (s, br, 1H). 13C NMR (125 MHz, DMSO-d6): δ (ppm) 49.4, 107.5, 110.4, 116.6, 120.1, 124.9, 127.0, 128.4, 129.3, 129.6, 135.5, 137.6, 143.1, 169.0.
