Reaction Steps

A mixture of N-[4-(4-aminophenyl)butyl]carbamic acid tert-butyl ester (4.5 g, 17 mmol) and 2-bromoethylamine hydrobromide (1.75 g, 8.5 mmol) in toluene was stirred at 100° C. for 3 days. The solvent was removed under reduced pressure and the residue was purified by flash chromatography (silica gel, chloroform/methanol/ammonium hydroxide, 8:1:0.1, v/v) to give 660 (1.47 g, 56%) as a white powder. 1H NMR (300 MHz, CD3OD) δ 1.42 (s, 9H), 1.51 (m, 4H), 2.48 (t, 2H), 2.85 (t, 2H), 3.03 (t, 2H), 3.17 (m, 2H), 6.59 (d, 2H), 6.94 (d, 2H). m/z (ESI) 308 [C17H29lN3O2+H].
