I have amidation reaction in DCM using DCC. I can separate the bi-product through centrifuge or filtration. I am wondering what is the best solvent to precipitate the product ? either using cold ethyl ether or cold MeOH ?
Dissolve your product mixture in hot polar solvent like methanol or chloroform then add drop wise ether or hexane tell soln. become cloudy then keep it in cold place , you will get crystallized product. Good luck.
