Synthesis
GENERAL METHOD: Benzyl halide (1 eq.) was dissolved in THF (50 mL/g benzyl halide) with reference to the method described in Ref. 4, to which 1.5 eq. of triethylamine (33 wt% ethanol solution) was subsequently added. The reaction mixture was stirred at room temperature for 24 h. The product precipitated as a white solid during the reaction. The resulting suspension was cooled to 0 °C, filtered, and the filter cake was washed with ice-cold ether and finally dried under vacuum to afford the target product benzyltriethylammonium bromide in a yield consistent with literature reports.
