Treatment of 2-amino-2-methylcyclohexanone with methyl 2,4-dibromobutanoate in the presence of a nonnucleophilic base, , involves two successive SN2 reactions and gives compound A. Propose a structural formula for compound A.

Explanation:

The proposed structural formula for compound A can be seen in the diagram below with its reaction mechanism. In the first SN2 reaction, we could see how anime reacts with the primary alkyl bromide since it is more reactive. However, the product derived undergoes a subsequent SN2 reaction in the second stage to produce a cyclic product.
