Water → Methyl 1-[(2,5-dimethylphenyl)acetyl]-4-piperidinecarboxylate

Participants

Reaction Steps

A solution of 2.86 g (20 mmol) of methyl isonipecotate and 2.53 g (2.5 mmol) of triethylamine in 10 mL of dry dichloromethane was cooled to 0° C., and a solution of 4.02 g (22 mmol) of 2,5-dimethylphenylacetyl chloride in 5 mL of dichloromethane was added dropwise. The mixture was stirred at room temperature for 16 h and then poured into 20 mL of water. The organic layer was washed with water and brine, dried (MgSO4) and concentrated under reduced pressure. The residue was crystallized from a mixture of ethyl acetate and hexanes to give 4.95 g (87.5% yield) of the title compound as white crystals.
