Step-by-Step Solution

Verified
Answer

The product lactam will get by several by-products from 5- aminopentanoic acid DCC




  

 


1Overall reaction to yield a lactam product

On reaction with 5- aminopentanoic acid DCC will get lactam product and Di phenyl dicarbametic as an addition product.


2Yield a lactam product from Protonated DCC

From the DCC and get protonated from amino acids.


3Yield a lactam product from lactam


By the process of nucleophilic attack by a nucleophile on the carbon and furthermore process the product lactam is produced.



4Yield a lactam product from lactam

And the process continues,



5Conclusion

Therefore, the product lactam will get from several by-products from 5- aminopentanoic acid DCC
