One possible synthetic sequence involves five steps. Steps $1$ and $2$ and steps $3$ and $4$ are carried out sequentially. The intermediate formed after steps $1$ and $2$ was isolated and was shown by ${?}^{1}HNMR$ to have only three types of chemically distinct hydrogen atoms. Identify the correct steps and their appropriate order in the synthesis.
