Komponenten

Versuchsvorschrift

A mixture of Ferulic acid (0.0083 mol), K2CO3 (10%, 3 ml), imidazole (1 mL) and dimethylformamide (15 ml) were taken in a 250 ml Erlenmeyer flask fitted with a loose funnel at the top. The flask was shaken well and placed inside the microwave oven over an ice bath and irradiated for 30 minutes in parts. After completion of reaction, it was worked up and purified as in example V and provided sweet and pleasant smelling viscous liquid. 59% yield; (Spectral data as in example V)
