Hantzsch-type reaction - Dean Stark

I set up a Hantzsch-type reaction. To this end, a mixture of the thioamide and the bromoacetone in toluene was refluxed overnight. Before that, I had tried several different conditions without success. Now, since the condensation between these two molecules involves the formation of water, I thought it would be a good idea to carry out this reaction in a Dean-Stark apparatus, in order to remove the water generated and drive the reaction toward completion. However, the reaction went south.

Classic experience in synthesis 😂

"yo dawg this simple reacc will work fr"

[@Alchemist_of_India]

Did you check the reaction mixture with TLC to decide whether the reaction failed or not

[@NROChemistry]

yes

[@alexandrupostole7234]

Sad

Why??? O please, don't worry. This is chemistry; things hardly ever work out your way. Just keep trying, till you find the proper conditions or a route that actually works. :)
