How can we successfully isolate and purify a synethesized product by performing a full work-up?
Homework Answers
First of all, We have to check the progress of the reaction by checking TLC periodically. After completion of the reaction, we have to do work-up by diluting with organic solvents like DCM or Ethyl acetate and water (1:3 ratio). Then, extract the organic layer, dried over Anhyd. Na2SO4 and concentrated under reduced pressure using rotavapour. Next, the crude reaction mixture can be purified by using Silicagel column chromatography in hexane : EtoAc solvent mixture to afford the desired pure synthesized product.
