Consider the synthesis of a compound with both a carboxylic acid and an alcohol functional group. How would you use protecting groups in organic synthesis to selectively modify only one of these functional groups while leaving the other intact during the synthesis process? Specifically, explain the steps and reagents used to protect and deprotect the functional groups in order to achieve the desired modification.
