Chemische Eigenschaften
Cyclopropylamine is a colorless and transparent flammable liquid with volatility and ammonia odor. It is miscible with water, methanol, ethanol, benzene, toluene and other solvents.
Verwenden
Cyclopropylamine is used in the preparation of N-[4-(4-fluoro)phenyl-2-aminothiazol-5-yl]pyrimidin-2-yl-alkylamine derivatives. It is also used to prepare Pt(CPA)2(bismethylthiomethylenepropanedioate) and Pt(CPA)2(bisethylthiomethylenepropanedioate) complexes.
Definition
ChEBI: Cyclopropylamine is a primary aliphatic amine that consists of cyclopropane bearing a single amino substituent. It has a role as a mouse metabolite.
Application
Cyclopropylamine is mainly used in organic synthesis, pharmaceutical synthesis intermediates, and can be used in the synthesis of new antibacterial drugs ciprofloxacin products, such as the synthesis of ciprofloxacin, enrofloxacin, spafloxacin and other drugs. In addition, cyclopropylamine is also an important intermediate for the synthesis of pesticides, plant protection agents and herbicides, such as 2-chloro-4-6-cyclopropyl-s-triazine, cyprochlor, cyproterazine, cyprocyanine and other cyclopropanes class of pesticides.
synthetische
Cyclopropylamine is synthesized from 1,3-propanediol by bromination, cyanation, cyclization, amidation, and Hoffmann rearrangement. It is also synthesized with γ-butyrolactone and isopropanol by five steps of ring-opening esterification, cyclization, hydrolysis, acylation and Hofmann degradation.
läuterung methode
It has been isolated as the benzamide m 100.6-101.0o (from aqueous EtOH). It forms a picrate m 149o (from EtOH/pet ether) from which the free base can be recovered using a basic ion-exchange resin and can then be distilled through a Todd column (p 11) using an automatic still head which only collects products boiling below 51o/atm. Polymeric materials if present will boil above this temperature. The hydrochloride has m 85-86o [Roberts & Chambers J Am Chem Soc 73 5030 1951, Jones J Org Chem 9 484 1944, Emmons J Am Chem Soc 79 6522 1957]. [Beilstein 12 IV 3.]
