Versuchsvorschrift
A solution of 4.8 g (0.039 mol) of 4-methoxymethyl-pyridine in 25 ml of acetonitrile is mixed with 6.6 g (0.047 mol) of methyl iodide and stirred for 5 hours at ambient temperature. Then the partially precipitated quaternary salt is precipitated by the addition of ethyl acetate. 9.1 g (88% of theory) of 4-methoxymethyl-1-methyl-pyridinium iodide are obtained, m.p. 105°-108° C.
