Application
TCI Practical Example: Buchwald-Hartwig Amination Using JohnPhos
Used Chemicals
Procedure
-
To a solution of sodium tert-butoxide (0.54 g, 5.6 mmol), palladium(II) acetate (4.5 mg, 0.020 mmol), and JohnPhos (0.012 g, 0.040 mmol) in toluene (8 mL) 4-chlorotoluene (0.51 g, 4.0 mmol) and morpholine (0.42 g, 4.8 mmol) were successively added at room temperature. The mixture was stirred under nitrogen atmosphere at room temperature for 1.5 days, then under reflux condition for 0.5 days. Diethyl ether (20 mL) was added to the reaction mixture and filtered through celite. Solvent was removed and the residue was purified by column chromatography (1:4 ethyl acetate / hexane on SiO2), giving 4-(p-tolyl)morpholine as a pale brown solid (0.45 g, 63% yield).
Experimenter's Comments
The reaction mixture was monitored by 1H NMR.
