4-Amino-4'-cyanobiphenyl → 4'-{[5-(3-Cyano-benzyloxy)-4,6-dimethyl-pyridin-3-ylmethyl]-amino}-biphenyl-4-carbonitrile

Participants

Reaction Steps

The reductive amination of 3-(5-formyl-2,4-dimethyl-pyridin-3-yloxymethyl)-benzonitrile (27) (10.0 g, 37.6 mmol) and 4-amino-4′-cyanobiphenyl (8.8 g, 45.1 mmol), as described in Example 21, gave 4′-{[5-(3-cyano-benzyloxy)-4,6-dimethyl-pyridin-3-ylmethyl]-amino}-biphenyl-4-carbonitrile (28) (5.0 g, 30% yield) as a colorless solid.
