crystalline solid | [Definition]
ChEBI: The monohydrochloride salt of chloroprocaine. Used as a local anaesthetic, particularly for oral surgery, it has the advantage over lidocaine of constricting blood vessels, so reducing bleeding. | [Originator]
Nesacaine,Astra,US,1956 | [Uses]
Anesthetic (local). | [Manufacturing Process]
In the first step, 2-chloro-4-aminobenzoyl chloride hydrochloride is prepared
by refluxing a mixture of 25 cc of purified thionyl chloride and 10 g of 2-
chloro-4-aminobenzoic acid until all of the solid has gone into solution. To the
cooled solution is added 150 cc of dry ethyl ether. A brisk stream of dry
hydrogen chloride is passed into the solution until the precipitation of 2-
chloro-4-aminobenzoylchloride hydrochloride is complete. The acyl halide is
removed by filtration and dried in a vacuum desiccator.
In the second step, the diethylaminoethyl 2-chloro-4-aminobenzoate
hydrochloride is prepared by refluxing equimolar proportions of the
hydrochloride of beta-diethylaminoethanol in a suitable inert solvent such as a
mixture of dry toluene and tetrachloroethane and the hydrochloride of 2-
chloro-4-aminobenzoyl chloride until the reaction as indicated by the cessation
of hydrogen chloride evolution is complete. The supernatant solvents are
decanted from the reaction product which can be conveniently purified by
crystallization from absolute ethanol.
An alternative purification can be effected by dissolving the reaction product in
water. The ester base is liberated by rendering the clarified aqueous solution
alkaline. Removal of the base from the alkaline solution is achieved by
extraction with a suitable solvent such as benzene or ether. The pure
hydrochloride of diethylaminoethyl 2-chloro-4-aminobenzoate is then
precipitated from the dried extract by the addition of dry hydrogen chloride.
After removal by filtration and recrystallization from ethanol it is found to
have a melting point of 173° to 174°C. | [Brand name]
