Abstract

1 min read

The title compound, C 20 H 19 N 3 O 2 , was synthesized by Stille coupling of ethyl 2,6-dibromoisonicotinate and 2-trimethylstannyl-5-methylpyridine. The three pyridine rings in the molecule are coplanar and the crystal packing revealsstacking interactions between these conjugated aromatic rings with a distance between the mean planes of 3.494 A .
