Procedure

To 2.0 M solution of ethylamine in THF (8 mL, 16 mmol) slowly added 4-chloro-N-(2-dimethylaminoethyl)-3-nitrobenzamide (0.40 g, 1.5 mmol). After heating at 65° C. for 16 h, the reaction mixture was cooled, concentrated and chromatographed (silica gel, MeOH/DCM, 3:22) to afford the title compound (0.30 g, 73%) as a yellow solid. 1H-NMR (CD30D): δ 8.75 (1H, d), 8.32 (1H, br s), 7.98 (1H, dd), 7.08 (1H, d), 3.58-3.64 (3H, m), 3.43-3.51 (2H, m), 2.94 (2H, br t), 2.62 (6H, s), 1.35 (3H, t).
