Incredible, my brother! How did you manage to crystallize such large blocks so quickly?

Thank you very much for sharing. I have some doubts. I hope you can help me answer them. Thank you!

1- Can DCM be used instead of ethyl acetate extraction?

2- Is it necessary to evaporate the solvent DCM+ (ethyl acetate) after drying with anhydrous magnesium sulfate? PH5.

3- Can isopropyl alcohol replace acetone when adjusting acid?

1. yes
2. DCM should preferably be distilled, crystallization is easier in ethyl acetate with acetone. However, you could use acidification into the aqueous layer and avoid evaporating the solvents, crystallizing the product from water or a mixture of water and alcohol/acetone
3. u can use no more than 5 parts IPA to one part acid to avoid problems with crystallizing all of the product

did you ever finish the project?
