Reaction Steps

A mixture of 2-chloro-5-nitropyridine (5.0 g, 31.5 mmol) and 40% solution of Dimethylamine (10.66 g, 95 mmol) in ethanol (40 mL) was heated to 75° C. for 1 hour. The mixture was cooled to ambient temperature, diluted with CH2Cl2 and washed with saturated aqueous NaHCO3 (3×100 mL) and brine. The organic was dried (MgSO4), filtered and concentrated to afford 5.27 g (100%) of the title compound. MS (ESI) m/z 168 (M+H)+.
