Show how p-toluidine can be converted to the following compounds, using any necessary reagents.


We have considered nucleophilic aromatic substitution of pyridine at the 2-position and 3-position but not the at the 4-position. Complete the three possible cases by showing the mechanism for the reaction of methoxide ion with 4-chloropyridine. Show how the intermediate is stabilized by delocalization of the charge onto the nitrogen atom.
Show how you would accomplish the following synthetic conversions.
(a) benzyl bromide to benzylamine
(b) 1-bromo-2-phenylethane to 3-phenylpropan-1-amine
(c) pentanoic acid to pentan-1-amine
(d) pentanoic acid to hexan-1-amine
(e) (R)-2-bromobutane to (S)-butan-2-amine
(f) (R)-2-bromobutane to (S)-2-methylbutan-1-amine
(g) hexan-2-one to 1-amino-2-methylhexan-2-ol
Within each structure, rank the indicated nitrogens by increasing basicity.



In Section 19-10B, we saw that pyridine undergoes electrophilic aromatic substitution reluctantly, requiring strong conditions and giving disappointing yields. In contrast, pyridine N-oxide undergoes EAS under moderate conditions, giving good yields of substitution on C2 and C4. Explain this surprising difference.
