Cesium carbonate → HCID 60980893, compound

Participants

Reaction Steps

To a stirred solution of ethyl isonipecotate (22.0 grams, 140 mmol) in acetonitrile (250 mL) at room temperature was added cesium carbonate (97 grams, 298 mmol) followed by 1-bromo-3-methoxypropane (20 mL, 154 mmol) and the reaction mixture was heated to reflux for 4 hours. The reaction mixture was cooled to room temperature and filtered through a small pad of celite. The volatiles were removed under reduced pressure to obtain ethyl 1-(3-methoxy propyl)piperidin-4-carboxylate (31.0 grams).
