Scheme-1: $C_{6} H_{5} N_{2} C l \overset{C u C N}{\to} C_{6} H_{5} C N \overset{H_{2} o / H^{+}}{\to} C_{6} H_{5} C O O H \overset{∆}{\to} [Product - I]$
Scheme-2: $C_{6} H_{5} N O_{2} \overset{F e / H C L}{\to} C_{6} H_{5} N H_{2} \overset{N_{2} N O_{3} + H C L, 273 K}{\to} C_{6} H_{5} N_{2} C l \overset{H_{2} O / H^{+}}{\to} [Product - II]$
Scheme-3: $C H_{3} C O O H \overset{N H_{3}}{\to} C H_{3} C O N H_{2} \overset{N a O B r}{\to} [Product - III]$ উল্লিখিত Scheme সমূহে Product-I, Product-II এবং Product-III হলো যথাক্রমেঃ

$C_{6} H_{5} C O O N H_{4}, C_{6} H_{5} C l a n d C H_{3} O H$

$C_{6} H_{5} C O N H_{2}, C_{6} H_{5} N H_{2} a n d C H_{3} O H$

$C_{6} H_{5} C O N H_{2}, C_{6} H_{5} N H_{2} a n d C H_{3} N H_{2}$

$C_{6} H_{5} C O N H_{2}, C_{6} H_{5} O H a n d C H_{3} O H$

$C_{6} H_{5} C O N H_{2}, C_{6} H_{5} O H a n d C H_{3} N H_{2}$
