1,2,4-Trimethylpyridin-1-ium iodide → HCID 58123891, compound

Participants

Reaction Steps

PhCH2MgCl (1 M in Et2O, 180 mL) is added dropwise to a solution of 1,2,4-trimethyl-pyridinium iodide (24.3 g) in Et2O(90 mL) chilled in an ice bath. After stirring in the ice bath for 2 h, the solution is poured into a mixture of 72% aqueous HClO4 (40 mL) and crushed ice (ca. 900 mL). The resulting mixture is stirred for 1 h and the precipitate formed is separated by filtration. The precipitate is washed with methanol and dried to afford the HClO4 salt of the title compound.
