Reaktionsschritte

To a solution of methyl 2-hydroxycinnamate (1.31 g; 7.33 mmol) in 50 ml acetone was added 1,3-dibromopropane (1.50 ml; 14.8 mmol) and K2CO3 (4.36 g; 13.4 mmol). The mixture was heated to reflux for 12 h, cooled to r.t, diluted with hexane (50 ml), filtered and finally concentrated to afford the title product (1.96 g; 50% pure), which was used as such in the next step.
