실험 절차

A solution containing aldehyde 23-2 (1.5 g, 10 mmol), ethyl hydrogen malonate (1.6 g, 20 mmol), and ammonium acetate (3.8 g, 50 mmol) in anhydrous ethanol (125 mL) was heated at reflux for 8 h. After cooling to room temperature, the solvent was evaporated and the residue partitioned between sat. sodium bicarbonate and EtOAc, the organic layer removed, dried, and concentrated. Chromatography of the residue afforded the amino ester 23-3 as a waxy solid.
