Buchwald–Hartwig amination: 5-Bromo-2-chloroanisole → Tert-butyl 2-(4-chloro-3-methoxyphenyl)-1,3,3a,4,6,6a-hexahydropyrrolo[3,4-c]pyrrole-5-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

90 °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.

A mixture of tert-butyl hexahydropyrrolo[3,4-c]pyrrole-2(1H)-carboxylate (205 mg, 0.97 mmol), 5-Bromo-2-chloroanisole (235 mg, 1.06 mmol), Sodium tert- butoxide (130 mg, 1.35 mmol), rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (30.1 mg, 0.05 mmol) and Tris(dibenzylideneacetone)dipalladium(0) (44.2 mg, 0.05 mmol) in toluene (10 mL) under a nitrogen atmosphere was stirred at 90 °C for 12h. The solution was washed with saturated NaHCO3 solution, brine, dried over sodium sulfate, filtered and concentrated under reduced pressure. The crude material was loaded on a 24g silica gel column and purified on a Teledyne Isco instrument, eluting with 20% to 40% ethyl acetate in heptane to provide tert-butyl 5-(4-chloro-3-methoxyphenyl)hexahydropyrrolo[3,4-c]pyrrole-2(1H)-carboxylate (220 mg, 64.6 %)
