Reaction Steps

A mixture of 2-ethyl-butylamine (4.5 g, 44.6 mmol) and 3-oxo-butyric acid methyl ester (5.8 mL, 53.5 mmol) in MeOH (170 mL) was refluxed for 2 h. Propynoic acid methyl ester (6 mL, 66.8 mmol) was added, and the resulting mixture was refluxed for 2 days. After cooling to r.t., the solvent was evaporated. The residue was purified by silica gel chromatography (0-30% EtOAc/hexanes) to give 7.32 g of the title compound as an orange oil. MS: (+) m/z 284.35 (M+1).
