Procedure
To a solution of 4-chloro-3-nitroaniline (1.0 g, 5.81 mmol) in 1:1 THF/DCE (200 mL) was added triethylamine (3.53 g, 34.9 mmol, Aldrich), 2-dimethylaminoacetyl chloride hydrochloride (1.82 g, 11.6 mmol, Alfa Aesar), and catalytic DMAP (Aldrich). After heating overnight at 65° C., the crude reaction mixture was diluted with dichloromethane (300 mL), washed with saturated NaHCO3 (50 mL), evaporated, and purified by column chromatography (dichloromethane to 5% methanol/dichloromethane) to provide N1-(4-chloro-3-nitrophenyl)-N2,N2-dimethylglycinamide (1.0 g, 67%) as a brown solid. ESIMS (M+H)+=258.
