Reaction Steps

3-Nitro-4-Chloro pyridine (10 mmol) dissolved in dichloromethane (25 mL) and diethyl iso propyl amine (20 mmol) followed Boc piperazine(10 mmol) was added to the above solution while cooling at 0° C. and the reaction mixture was stirred at room temperature for overnight . The dichloromethane was evaporated under vacuum. The resulting solid is extracted in to dichloromethane and washed with citric acid and brine solution. The evaporation of dichloromethane gave a yellow solid, 4-(3-Nitro-pyridin-4-yl)-piperazine-1-carboxylic acid tert-butyl ester which is used for next step without purification.
