edit- The amides are the least reactive of the carboxylic acid derivatives, in part because they are strongly stabilized by delocalization of the nitrogen lone pair (...) As a consequence, their nucleophilic addition – eliminations require relatively harsh conditions. For example, hydrolysis to the corresponding carboxylic acid occurs only upon prolonged heating in strong aqueous acid or base by addition – elimination mechanisms. Acid hydrolysis liberates the amine in the form of an ammonium salt.

- In contrast to carboxylic acids and esters, the reaction of amides with lithium aluminum hydride produces amines instead of alcohols. (...) The mechanism of reduction begins with hydride addition, which gives a tetrahedral intermediate. Elimination of an aluminum alkoxide leads to an iminium ion.Addition of a second hydride gives the final amine product. (...) Reduction of amides by bis(2-methylpropyl)aluminum hydride (diisobutylaluminum hydride) furnishes aldehydes.
