I have run quite a lot of reactions in DMF and basically used two ways to remove it. The first one was to pour my reaction mixture in water, extract with ether or ethylacetate my compound and wash with water (at least three time). In some cases the compounds was precipitating in water, so just collecting it on a frit, washing of the solid with water. In these case, a simple recryst was enough to get my compound pure and free of DMF.
the second option I used was to remove the DMF by bulb to buld distillation ( bath at 60°C, oil pump vacuum) and trapping the DMF into a liquid nitrogen cooled trap. I tried on a rotavap but it was not convenient. the residue was then dissolved into ether or ethylacetate and washed extensively with water.
note that my compounds were neither volatiles or water soluble.
