Hydrochloric Acid → cis-(4-Methylpiperidin-3-yl)(pyrrolidin-1-yl)methanone

Participants

Reaction Steps

Saturated ethereal hydrogen chloride (40 mL) was added to a solution of cis-tert-butyl 4-methyl-3-(pyrrolidine-1-carbonyl)piperidine-1-carboxylate (2.6 g, 8.78 mmol) in ether (20 mL) at 0° C. The reaction mixture was stirred at room temperature for 2 h. The solvent was removed under reduced pressure to afford cis-(4-methylpiperidin-3-yl)(pyrrolidin-1-yl)methanone (1.7 g).
