I am conducting a synthesis involving Buchwald–Hartwig amination. Catalyst is $\ce{Pd2(dba)3},$ ligand is $\ce{P(o-tol)3},$ base is $\ce{Et3N},$ and solvent is toluene. Image below is the proposed mechanism.
I used $\ce{Et3N}$ as base, so I assume that an ionic compound $\ce{(Et3NH)+Br-}$ is formed. Should I do solvent extraction with water to remove triethylamine hydrobromide?
I couldn't find any procedures in the literature, although some papers mention Celite filtration.
