Buchwald–Hartwig amination: 3-Bromo-2-methylpyridine → Tert-butyl 4-(2-methylpyridin-3-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.

Temperature

100 °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.

Palladium acetate (65 mg, 0.29 mmol) and RuPhos (271mg, 0.58mmol) were dissolved in toluene (10 mL), degassed and purged with nitrogen and warmed to 50°C for 15 minutes. In a separate vessel, were mixed 3-bromo-2-methyl pyridine (1.00g, 5.81 mmol), BOC-piperazine (1.08g, 5.81mmol), sodium tertbutoxide and toluene (17 mL). The mixture was degassed, purged with nitrogen and warmed to 50°C. The catalyst was transferred to the reaction vessel and the mixture degassed and purged with nitrogen. The reaction was heated at 100°C overnight under nitrogen. The mixture was filtered through GF/F paper, washing with MeOH. The filtrate was concentrated to provide a dark brown gum. The gum was purified by flash silica chromatography, elution gradient 30 to 80% EtOAc in heptane. Pure fractions were ev
