Carbonyl and amino group can easily generate Schiff base (imine), the reaction is a dehydration reaction, the carboxyl and hydroxyl groups in the reactants have no effect on the reaction, please note:

The most commonly used solvents are ethanol or methanol

Advantageous reactions need to be heated or added to activate the carbonyl group by adding Lewis acid

3. Reactants and solvents try to select the dehydrate
