Reduction of aldehyde to imine

The aldehyde is reduced to imine when the amine attacks the carbonyl carbon. The lone pair of electrons moves from the amine group to the electron-deficient group of C=O.  

Reduction of imine to amine

The reduction of imine to amine is completed in the presence of reducing agents, such as lithium aluminum hydride, sodium cyanoborohydride, etc. The reducing agents produce hydride in the deficient groups.
