(2R)-2-[(3,4-dimethoxyphenyl)methyl]pyrrolidine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of (R)-2-(3,4-dimethoxybenzyl)-1-trifluoroacetylpyrrolidine (3.2 g, 0.010 mol) in 50 mL isopropyl alcohol was added 15 mL of 12.5M HCl. The mixture was then heated under reflux until all starting material had disappeared, approximately 24 hours. The solvent was removed in vacuo to give an oil which could be recrystallized from isopropyl alcohol/ether, giving 2.5 g of (R)-2-(3,4-dimethoxybenzyl)pyrrolidine (97% yield), as needles, m.p. 165°-167° C. The mixture was then heated under reflux until all starting material The solvent was removed in vacuo to give an oil which could be recrystallized from isopropyl alcohol/ether

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
