Write balanced reaction equations separately for each of the four steps of your reaction (listed below). just give the balanced overall equation, not the mechanism. include all counter ions and side products as well as the major reactants and products.
a. formation of the n-butyl bromide grignard reagent
b. magnesium-halogen exchange reaction to make the 4-bromo-n, n-dimethylaniline into a grignard reagent
c. reaction of the grignard reagent with the ester you are planning to use. do not include the addition of hcl step.
d. reaction of the product from (c) with hcl
