Buchwald–Hartwig amination: 2-Chloro-4-iodo-5-(trifluoromethyl)pyridine → 2-[2-Chloro-5-(trifluoromethyl)pyridin-4-ylamino]-N-methylbenzamide

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.

2-chloro-4-iodo-5-(trifluoromethyl)pyridine (7 g, 22.77 mmol), 2-amino-N- methylbenzamide (3.42 g, 22.77 mmol), diacetoxypalladium (0.409 g, 1.82 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (2.108 g, 3.64 mmol) and cesium carbonate (8.90 g, 27.32 mmol) were mixed together in dioxane (140 mL). Reaction was degassed with nitrogen and was stirred at 90 °C overnight under nitrogen. Reaction was filtered, washed with CH2Cl2 and filtrate was concentrated to dryness. The crude product was purified by flash chromatography on silica gel eluting with 10 to 50% ethyl acetate in petroleum ether. The solvent was evaporated to dryness to afford 2-(2-chloro-5-(trifluoromethyl)pyridin-4-ylamino)-N-methylbenzamide (5.06 g, 67.4 %) as a pale yellow solid.
