(S)-(1-Ethylpyrrolidin-2-yl)methanamine, cas is 22795-99-9, it is a common heterocyclic compound, the chiral-catalyst compound, its synthesis route is as follows.,22795-99-9
In a 100 mL eggplant bottle, 1.22 g of benzaldehyde, 30 mL of anhydrous ethanol,(S) -1-ethyl-2-aminomethyltetrahydropyrroline, and the mixture was heated under reflux for 24 hours. Adding 0.76 g of sodium borohydride, stirring for 3 hours, pouring into water, extracting the organic phase with dichloromethane,Dried over anhydrous magnesium sulfate, and the solvent was removed to obtain a pale yellow viscous liquid.30 mL of absolute ethanol, 0.6 g of paraformaldehyde, 1.63 g of 2,4-dichlorophenol were added, and the mixture was heated under reflux for 12 hours.The crude product was chromatographed on silica gel to give red liquid L1 (2.32 g, 59.0percent).
22795-99-9 is used more and more widely, we look forward to future research findings about (S)-(1-Ethylpyrrolidin-2-yl)methanamine
