please help me :)

3. The compound 4-dimethylaminopyridine (DMAP) is an excellent catalyst for esterification reactions. In the presence of one equivalent of a non-nucleophilic base, only a substoichiometric amount (about 5 mol \%) of DMAP is required to dramatically accelerate the reaction rate. Using ChemDraw, provide a complete mechanism, showing all intermediates, for the reaction shown in question 2 using 5 mol % DMAP as catalyst and stoichiometric amounts of divisopropylethylamine (/Pr2EtN) as a Bronsted base. Be sure to consider relative pKa values in your answer. 3. The compound 4-dimethylaminopyridine (DMAP) is an excellent catalyst for esterification reactions.
