Preparation: 2-Methylpyridine was the first pyridine compound reported to be isolated in pure form. It is now mainly produced by two principal routes, the condensation of acetaldehyde, formaldehyde, and ammonia and the cyclization of nitriles and acetylene. One example of such reaction is the combination of acetaldehyde and ammonia:

such reaction is the combination of acetaldehyde and ammonia

Uses of 2-Methylpyridine: it is a versatile building block and can be used as a precursor to a variety of derivatives. For example, oxidation by potassium permanganate affords picolinic acid:

oxidation by potassium permanganate affords picolinic acid
