Procedure

Ethyl phenylacetate, 49.2 g was added to a solution of sodium ethoxide previously prepared from metallic sodium, 2.9 g and ethanol, 100 ml. The mixture was cooled to 5°, then a solution of 2-methylenequinuclidin-3-one, 39.4 g, in ethanol, 50 ml, was added dropwise and with stirring. After 16 hours at room temperature, the solution was neutralized with acetic acid then subjected to evaporation at reduced pressure. Water, 100 ml. water added to the residue and the mixture was extracted with chloroform. Evaporation of this solvent gave ethyl (3-oxoquinuclidin-2-yl)methylphenylacetate, 54 g (60%): b.p. 195°-200° at 1 mm Hg; m.p. of methiodide salt, 194.7°-195.6°.
