Crystal structure of 2-benzylamino-4-p-tolyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile

The title compound, C23H21N3, comprises a 2-amino-3-cyanopyridine ring fused with a cyclopentane ring. The later adopts an envelope conformation with the central methylene C atom as the flap. The benzyl and and p-tolyl rings are inclined to one another by 56.18 (15)°, and to the pyridine ring by 81....
