Reaction Steps
To a solution of 4-chloro-3-nitro-pyridine (18.0 g, 114 mmol) in EtOH(300 ml) is added n-propylamine(46.9 ml, 568 mmol) slowly at 0° C. and the resulting yellow mixture is warmed to room temp. After stirring for 2 h, the reaction is concentrated in vacuo. The residue is purified by flash chromatography (eluent 50% Hex/EtOAc) to give (3-nitro-pyridin-4-yl)-propyl-amine as a yellow solid. 1H NMR (CDCl3) δ 9.16 (s, 1H), 8.25 (d, J=6 Hz, 1H), 8.15 (br s, 1H), 6.68 (d, J=6 Hz, 1H), 3.29 (q, J=6.8 Hz, 2H), 1.74 (sextet, J=7.2 Hz, 2H), 1.02 (t, J=7.6 Hz, 3H). LRMS calcd 181.19, found 182.5 (MH+).
