With both chloro and cyano functional groups, it is a bifunctional molecule.
Cyclopropyl cyanide is prepared by reaction of 4-chlorobutyronitrile with sodium amide in liquid ammonia.
This in turn is a chief precursor to a family of compounds called pyrroloisoquinolines.
These are valuable agents in medicinal chemistry that are endowed with BAT substrate reuptake inhibitor properties, elevating the synaptic concentration of serotonin and/or catecholamines.
More recently, an alternative synthetic protocol was also reported by Maryanoff.
