実験手順
Methyl-4-methoxyacetoacetate (9 ml, 70 mmol) was added to dimethylformamide dimethylacetal (18.8 ml, 139 mmol) and the reaction stirred at 90° C. for 2 hours before cooling to room temperature and stirring for 18 hours. The reaction was concentrated in vacuo and purified by silica gel column chromatography, eluting with 70:30 to 100:0 ethyl acetate:heptane to afford the title compound as an oil (7.68 g, 50% yield).
