TLC (10 methanol PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/21034305 in chloroform, Rf = 0.three) confirmed the completion with the reaction by disappearance on the starting off location. Following elimination of your solvent, the residue was neutralized with three N HCl to pH = 3 and extracted with ethyl acetate.
