Synthesis following imine from aniline. You can use only use following compounds as reagents.
NaNO2, dilute HCl, LiAlH4, PCC, ether, H2O, KCN
Imines are prepared by the reaction of carbonyl compound (aldehyde or ketone) and primary amine such as methanamine, aniline. A water molecule is eliminated in this reaction when imine is given.
In this question, our target is synthesis an amine compound from aniline.
Aniline is a promary amine compound and benzaldehye is an aldehyde. In the reaction, two hydrogens of aniline (in -NH2) and oxygen atom which is connected to the carbonyl carbon are eliminated as a water molecule to give imine.
