Reaction Steps

Step 2) 3-Nitro-4-boc piperizinyl pyridine 3 (37 g, 0.12 mol) was dissolved in DCM (500 mL). The resulting solution was subjected Pd/C (10%, 14.8 g) and was kept under hydrogen atmosphere at room temperature. Overnight stirring and monitored the reaction progress until the reaction is complete. The reaction solution was filtered through celite, washed with DCM/MeOH and concentrated to give the product, 4-(3-Amino-pyridin-4-yl)-piperazine-1-carboxylic acid tert-butyl ester 4 (33 g) in the yield of around 99%.
