Purification

That's right! Upon the addition of HCl, your product molecule should be protonated and therefore dissolved in the organic layer.

Once you have isolated the organic layer, dry the layer with a small amount of sodium sulfate and spot a sample of solution on a TLC plate.

video shows a plastic centrifuge tube approximately two thirds full of clear liquid being uncapped; a pipette is then inserted into the upper layer of liquid and used to remove a portion of the liquid and place it in a large test tube clamped to a nearby post; two more portions of liquid are pipetted into the large test tube before the centrifuge tube is seen again, this time with a larger volume of liquid inside, implying that some additional material has been added in between shots; the pipette is once again to transfer three portions of liquid from the upper layer of the centrifuge tube into a large test tube; next we see a metal spatula placing white powder from a brown reagent bottle labeled “sodium sulfate” into the large test tube; the contents of the test tube are swirled but the white powder remains clumped at the bottom

What should you do next?

Evaporate off the ether.

Add more sodium sulfate.
