The authors comment that the synthesis of heterocycles in ball mills is a problematic reaction since most of the formations include a condensation step and liberate water, which cannot be removed from the closed vessel system. However, there are many examples of such syntheses taking advantage of the thermodynamic stability of the formed products.
