Collect the lidocaine precipitate by vacuum filtration.
Rinse the solid with small portions of cold water and draw air through it to aid drying (Use high vacuum).
Allow this sample to air dry in your drawer until the next lab.

Synthesis Of Lidocaine
WHAT IS LIDOCAINE?
is a crystalline compound that is used in the form of its hydrochloride as a
and as an
- It is the first amino amide- type local anesthetic, was first synthesized under the name
by swedish chemist Nils Lofgren in 1943.
- Trade names for this substance include Xylocaine, Isocaine, and Anestacon, and its systematic chemical name is 2-(diethylamino)-N-(2’,6’-dimethylphenyl)acetamide.
I sold / gave drugs to someone who then overdosed and died. What is going to happen? Many law enforcement agencies now aggressively investigate overdose deaths in order to build a case against the person(s) that provided the drug(s) to the deceased. If they are able to build a case (often through cell phone / text message records), the person providing the drugs may be charged with in some jurisdictions or simply with delivery of a controlled substance. Often times, the prosecutor will be seeking a substantial prison sentence with a threat of referring the case to federal court for prosecution (where the penalties are much more severe) under the so-called "Len Bias Law."

or by a combination of extraction and chemical synthesis: ..
What three roles does diethyl amine serve in this synthesis?
As a nucleophile to displace chloride anion from –CH2Cl in the α-chloro-2, 6-dimethylacetanilide by an SN2 type reaction;
As a base to absorb the HCl that is formed in the nucleophilic substitution reaction leading to lidocaine; and
As a solvent for the reaction.
