Esters can also be synthesized by transesterification

In this procedure we shift the equilibrium to the right by allowing the low-boiling alcohol to distill from the reaction mixture. The mechanism for transesterification is similar to that for an acid-catalyzed esterification (or an acid-catalyzed ester hydrolysis). Write a detailed mechanism for the following transesterification:

HA, heat ROH R' R OR" R OR High-boiling ester High-boiling Higher boiling ester Lower boiling alcohol alcohol HA OH OCH3 Methyl acrylate + CH,OH Methanol Butyl alcohol Butyl acrylate (94%)
