Reaction Steps

A mixture of 2-chloro-5-nitropyridine (1.0 g, 6.3 mmol), (R)-3-methyl-piperazine-1-carboxylic acid tert-butyl ester (1.26 g, 6.31 mmol), and potassium carbonate (2.18 g, 15.77 mmol) was stirred in DMSO (5 mL) at 120° C. overnight. The reaction mixture was concentrated under rotary evaporation and mixed with water (50 mL). The resulting precipitate was filtered, washed with water (3×10 mL) and air-dried to provide the title intermediate.
