Reaction Conditions

Reaction Steps

Diacetoneamine hydrogen oxalate (4.25 g) and methyl 4-oxobutanoate (2 g) were suspended in methanol (20 ml). The reaction mixture were stirred at 100° C. for three hours and then at room temperature overnight. It was then evaporated and the residue was purified by Combiflash chromatography (2.0 M ammonia methanol in dichloromethane=0-30%) to give methyl 3-(6,6-dimethyl-4-oxopiperidin-2-yl)propanoate (1.35 g, 37%).
