Into a 50-mL round-bottom flask, was placed a solution of 1-(4-nitro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperidine (600.0 mg, 1.81 mmol, 1.00 equiv) in ethyl acetate (30.0 mL), then Palladium carbon (10%) (150 mg) was added next. The gas of H2 was introduced in. The resulting solution was stirred for 1 h at 0=5° C. The Pd/C was filtered out and the filtrate was collected and concentrated under vacuum. This resulted in 545.8 mg (99%) of 4-(piperidin-1-yl)-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzenamine as a green to yellow solid. The target product was unstable, it was used to the next reaction step rapidly
