2,6- lutidine (2,6- dimethylpyridine ) is an organic compound that the heterocycles (more precisely, heteroaromatics ) counts. It consists of a pyridine ring which is substituted with two methyl groups. It belongs to the group of lutidine, a group of six constitutional isomers with the formula C7H9N.

2,6- lutidine was isolated from coal tar, and bone oil. It has a characteristic nutty smell.

The representation is analogous to the Hantzschschen Dihydropyridine from ethyl acetoacetate (as β - ketocarbonyl ), formaldehyde and ammonia in a ratio of 2:1:1 in the presence of diethylamine something. By oxidation of the methyl groups is formed, the dipicolinic acid.

In organic synthesis, the 2,6-lutidine, for example in the deprotection of alcohols is used as sterically hindered base such as the silyl ether.
