Which of the following amines can be prepared by Gabriel phthalimide reaction?
Options
- At - b u t y l a m i n e
- Bn - b u t y l a m i n e
- Ct r i e t h y l a m i n e
- Dn e o - p e n t y l a m i n e
Correct answer
B. n - b u t y l a m i n e
Step-by-step solution
Gabriel phthalimide is used to prepare primary amine. In first step S N 2 reaction takes place which is possible in less stearically hindered chloride. Alkyl chloride required for other amines has high stearic hindrance therefore, stearically hindered amine can't be produced from those alkyl chlorides.
