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
