Axtually, it turns out the dessicator method is the easy way to go. I just put my product in a beaker and purged the dessicator with vacuum and nitrogen. Although, I'm not sure how long to leave the product in the dessicator... Do you know how long it usually takes.. There is some condensation on the top of the dessicator, perhaps solvent left over from the product? It is supposed to be a DMF salt.
