Buchwald-Hartwig Amination Reaction in Water at Room Temperature using TPGS-750-M (Lipshutz Surfactant).

The catalyst [(π-allyl)PdCl]2 (2 mg, 0.006 mmol, Note: this component has been overweighed to account for some residual material left in the vial), ligand cBRIDP (8 mg, 0.022 mmol), KO-t-Bu (180 mg, 1.6 mmol), and amine (1.25 mmol) are sequentially added under argon into a reaction flask containing a stir bar. The TPGS-750-M/H2O (1.0 mL, 2 wt % TPGS-750-M in water) and aryl bromide (1.00 mmol) are added by syringe, and the resulting solution is stirred vigorously at room temperature for 19–20 h. The homogeneous reaction mixture is then diluted with EtOAc (2 mL) and filtered through a bed of silica gel, and the bed is further washed (3 x 5 mL) with EtOAc to collect all of the coupled material. The volatiles are removed in vacuo to afford the crude product that is subsequently purified by flash chromatography on silica gel.
