Tyramine is an alkaloid found in mistletoe and ripe cheese. Dopamine is a neurotransmitter involved in the regulation of the central nervous system.

c. Give two ways to prepare b-phenylethylamine from b-phenylethyl chloride.

Show how the following compounds can be synthesized from benzene:

h. p-nitro-N-methylaniline

Show how each of the following compounds can be synthesized from benzene:

a. How can tyramine be prepared from b-phenylethylamine?

Tyramine is an alkaloid found in mistletoe and ripe cheese. Dopamine is a neurotransmitter involved in the regulation of the central nervous system.

b. How can dopamine be prepared from tyramine?

Tyramine is an alkaloid found in mistletoe and ripe cheese. Dopamine is a neurotransmitter involved in the regulation of the central nervous system.

d. How can b-phenylethylamine be prepared from benzyl chloride?

Ibuprofen is the active ingredient in pain relievers such as Advil, Motrin, and Nuprin. How can ibuprofen be synthesized from benzene?

Pyrrole undergoes electrophilic aromatic substitution more readily than benzene, and mild reagents and conditions are sufficient. These reactions normally occur at the 2-position rather than the 3-position, as shown in the following example.

a. Propose a mechanism for the acetylation of pyrrole just shown. You may begin with pyrrole and the acylium ion, CH3C≡O+. Be careful to draw all the resonance structures of the intermediate.

Suggest a synthesis of each of the molecules shown beginning with benzene.
