How do I uninstall Dmpu?
The solids are removed by vacuum filtration through a course-fritted glass Buchner funnel and washed with ether (20 mL). The filtrate is then concentrated by rotary evaporation (30 °C, 74 mmHg) to give a colorless oil. The aqueous layers are combined and set aside for later recovery of DMPU, if desired (Note 22).

How do I remove DMSO solvent?
To remove DMSO, a common method is to wash with water and extract with a lower boiling point organic solvent like DCM1. Other methods involve freeze drying (lyophilization) after water dilution or solid phase extraction (SPE).
How do you remove THF from a reaction mixture?
Tricky Reaction Solvents: Remove the solvent by rotoevaporation first. several times, they will partition into the aqueous layer. However, sometimes product goes along with them, and sometimes emulsions form. It is safer to remove THF by rotoevaporation before workup if practical, especially for large scale procedures.
