반응 단계
To a vigorously stirred, ice-water cooled suspension of 2.0 g of 3-carbethoxy-4-piperidone in 20 ml of aqueous sodium carbonate is added 1 ml of acetic anhydride. The mixture is stirred in the cold for 30 minutes then extracted with ether. The organic layer is dried and evaporated to afford 1.5 g of colorless solid, m.p. 53°-55° C.
