(B) Step $1$: The reduction of $4	ext{-aminobenzonitrile}$ with $DIBAL-H$ $(AlH(i-Bu)_2)$ followed by hydrolysis yields $4	ext{-aminobenzaldehyde}$

Vedclass · Accepted Answer

$4	ext{-aminocinnamaldehyde}$

Vedclass · Answer

(B) Step $1$: The reduction of $4	ext{-aminobenzonitrile}$ with $DIBAL-H$ $(AlH(i-Bu)_2)$ followed by hydrolysis yields $4	ext{-aminobenzaldehyde}$ as product '$A$'.Step $2$: The reaction of $4	ext{-aminobenzaldehyde}$ with acetaldehyde $(CH_3CHO)$ in the presence of dilute $NaOH$ and heat is a cross-aldol condensation reaction.Step $3$: The aldehyde group of $4	ext{-aminobenzaldehyde}$ reacts with the $\alpha	ext{-hydrogen}$ of acetaldehyde to form $4	ext{-aminocinnamaldehyde}$ as the major product '$B$'.

Consider the following reaction sequence:
$4\text{-aminobenzonitrile}$ $\xrightarrow[(ii) H_2O]{(i) AlH(i-Bu)_2} 'A'$ $\xrightarrow[dil. NaOH, \Delta]{CH_3CHO} B$
The product $B$ is?
