Reaction Steps

A mixture of 2-bromo-N-tert-butyl-3-nitrobenzamide (460 mg, 1.52 mmol) and cyclopropanamine (350 μL, 4.55 mmol) in THF (10 mL) was heated at 60° C. for 18 h. The reaction mixture was diluted with EtOAc, washed with water, brine, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by flash chromatography on silica gel using EtOAC:DCM (1:1) as eluent to give N-tert-butyl-2-(cyclopropylamino)-3-nitrobenzamide: 1H NMR (400 MHz, CDCl3) δ 8.26 (1H, br), 8.09 (1H, dd, J=8.0, 4.0 Hz), 7.57 (1H, d, J=8.0 Hz), 6.72 (1H, t, J=8.0 Hz), 5.81 (1H, br), 2.98-2.92 (1H, m), 1.49 (9H, s), 0.82-0.76 (2H, m), 0.58-0.52 (2H, m); LC-MS (ESI) m/z 278.2 [M+H]+.
