Buchwald–Hartwig amination: 5-(Benzyloxy)-2-chloropyridine → Tert-butyl 4-(5-(benzyloxy)pyridin-2-YL)piperazine-1-carboxylate

Drawn from the record's atom map: which bonds break and which form between the reactants and products the source listed. It shows a change in connectivity, not a simulated trajectory and not a mechanism.

80 °C

Only the dimensions the source stated are listed. Anything absent here was not recorded, and it is not inferred from what the class usually needs.

No other run in the library makes this product. These runs of the same class start from one of the same reactants, which is the nearest company this record has.

BIS(DIBENZYLIDENEACETONE)PALLADIUM (0.055 g, 0.10 mmol) was added to tert- butyl piperazine-1-carboxylate (1.952 g, 10.48 mmol), 5-(benzyloxy)-2-chloropyridine (2.093 g, 9.53 mmol), 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (0.059 g, 0.10 mmol) and sodium 2-methylpropan-2-olate (1.282 g, 13.34 mmol) in toluene (30 mL) at 20ºC under nitrogen. The resulting solution was stirred at 80 °C for 16 hours then cooled to room temperature. The reaction mixture was filtered through celite, filtrate partitioned between ethyl acetate (100 mL) and water (100 mL). The organic phase was dried (Na2SO4), filtered and evaporated to give a brown gum. The crude product was purified by flash silica chromatography, elution gradient 0 to 20% EtOAc in isohexane. Pure fractions were evaporated to dryness to affor
