As a common heterocyclic compound, it belong chiral-catalyst compound,(S)-(1-Ethylpyrrolidin-2-yl)methanamine,22795-99-9,Molecular formula: C7H16N2,mainly used in chemical industry, its synthesis route is as follows.,22795-99-9
Reaction 5:In the glovebox, 500 ?? of the stock solution was transferred to the vial called chamber 2 of our 2-chamber system. Then an injection vial with the 5A MS (750 mg) was installed in the chamber 2 and the system was sealed with a crimp-cap (Aluminium Cap 20mm, silicone/PTFE). Palladium catalysed [nC]carbonylation reactions was then run following the previous described protocol. 307 MBq of crude product was isolated after flushing of the 2-chamber system. Analytical HPLC was run on an aliquot of the crude (Phenomenex Luna 5? C18 100A, 250×4.6 mm 5 micron, 35percent Acetonitrile 65percent NaH2P04 70mM, 2 mL/min). The HPLC chromatogram from the radio-channel showed that the desired[nC]raclopride was 11percent radiochemically pure.
With the synthetic route has been constantly updated, we look forward to future research findings about (S)-(1-Ethylpyrrolidin-2-yl)methanamine,belong chiral-catalyst compound
