Answer»

`(2^@ ) R-Br + NH_3 `
`(2^@ ) R-Br + NaCN `FOLLOWED by `H_2 //PT`
`(1^@ )R-NH_2 +RCHO `followed by `H_2//Pt`
`(1^@ )R-Br (2 mol) `+ potassium phthalimide followed by `H_(3)O^(+)`/heat.

Solution :`R-NH_2+ RCHOunderset("amination ") OVERSET("Reductive ")to [R -N= CHR ] overset(H_2 //Pt)tounderset( 2^@"AMINE")(R-NH -CH_2 R )`
