The syntheses are presently conduced commercially in the presence of oxide catalysts such as modified alumina (Al 2 O 3) or silica (SiO 2). The reactants are passed over the catalyst at 350-500 °C. 2-Methylpyridine- and 4-methylpyridine are produced as a mixture from acetaldehyde and ammonia.
Methylpyridinium is prepared by treating pyridine with dimethylsulfate: [2]. C 5 H 5 N + (CH 3 O) 2 SO 2 → [C 5 H 5 NCH 3] + CH 3 OSO − 3. It is found in some coffee products. [3] It is not present in unroasted coffee beans, but is formed during roasting from its precursor chemical, trigonelline. [3]
