Starting only from organic reagents of 4 carbons or fewer, propose an efficient synthesis for the molecule below. You may use any necessary solvents and inorganic reagents, and can assume that all products can be isolated as needed. If only one product is to be taken on to a new step, indicate which one.

Give a reasonable synthesis for
each of the following compounds from the indicated starting
materials. You may use any other organic or inorganic reagents you
wish unless otherwise indicated. The desired product for each
reaction you propose must be the one of the predominant products.
Give the reactants, conditions (where appropriate) and products of
each synthetic step. If equal mixtures are anticipated (i.e. ortho
/ para products) then indicate where separations are needed. NO
