Solution
\[\begin{array}{cc}
\phantom{.............................}\ce{Cl}\\
\phantom{.................................}\backslash\\
\ce{CH3 - C ≡ N + CH3MgCl -> CH3 - C = NMgCl + 2H2O ->[H+] Mg + NH3 + CH3 -C - CH3}\\
\phantom{................................}|\phantom{.......................}/\phantom{....................}||\phantom{..}\\
