Participants

Reaction Steps

To 100 mL of methanol is added 5.7 g (0.1 mol) of 2-propen-1-amine, 9.8 g (0.1 mol) of cyclopentanecarboxaldehyde and 12 g (0.2 mol) of sodium cyanoborohydride. Adjust the pH to 6 with concentrated HCl and monitor the reaction with thin-layer chromatography. Upon completion add concentrated HCl until gas evolution ceases. Add 300 mL of H2O and extract once with 200 mL of ether. Add 1N NaOH to the aqueous solution until it is basic and extract twice with 200 mL of ether. Dry the organic phase over Na2SO4. Filter off the drying agent and remove the solvent in vacuo to obtain the title compound.
